Blog #1: Drosophila Melanogaster
COMMENTS ARE NOW CLOSED ON THIS POST. TO TURN THIS POST IN LATE, PLEASE ANSWER THE QUESTION ON A SHEET OF PAPER AND TURN IT IN TO MRS. RAWSON.
Today in class, we watched a video about the fruit fly (Drosophila melanogaster). Over the next nine weeks, you will get very familiar with these organisms as we breed flies with different traits and observe their offspring.
For this blog, answer the following question in at least 3 complete sentences:
Why do scientists use Drosophila melanogaster for their research, and what types of questions or problems are these organisms being used to answer?
This blog assignment is due Monday, January 12.

Scientist uses Drosophila Melanogaster for their research because these organisms have the same type of DNA as humans, resulting in an easy research project. Also, while it may take 9 months for a human to reproduce, it takes Drosophila Melanogaster only a few days (or about a week or so). These organisms are being used to answer questions such as genes, how do the genes affect one another. They also are trying to use the organisms to help them find a cure to Alzheimer’s. Scientist is trying to make a drug or medicine that will help people remember more.
January 5th, 2009 at 5:27 pm
The sciencetist use the flys because they have notiable geans. They have tried to find a cure for alt timers. They found out that they can become mutana like as because they shair geans with us.
January 5th, 2009 at 6:41 pm
D. Melanogaster are used because it is easier to see their changes in behavior and they produce faster. These flies are used to answer the question about Altheimer diesease and if there is a cure. Also they are answering weather the personalitiy and looks of the parents, affect their offspring.
January 5th, 2009 at 8:34 pm
I think that they use this 4 research because:
1. it is easy to hold and handle
2. its not harming
3. they get better data.
People may ask how can you cure people with memory problems. Well to scientists its very simple they put all the fruit flies into a tube and they vacuumed in a licorice smell and whenever they went to it they got shocked. The next time they vacuumed in a smeel of smelly shoes in and they didnt get shocked. The next time they vacuumed both in and the all went to the one that didnt shock so they remembered what didnt shock them
January 5th, 2009 at 8:36 pm
I believe that scientist are gathering information relating to memory. they believe that fruit flies have sum kind of chemical that could come in handy to humans in the future. a problem about this is that the research or results could end up being used for the wrong reasons
January 5th, 2009 at 9:11 pm
Scientist use Drosophila as a genetic model to study human diseases because:
• The cultures don’t require much equipment and storage space and the cost is low.
• It is small, easy to grow, and has a short generation time.
• The females lay many eggs in a lifetime.
• Males and females are easily told apart, helping with genetic studies.
• They have only four pairs of chromosomes with visible genetic markers.
These organisms help answer questions in genetics, physiology, and life history evolution.
January 5th, 2009 at 9:21 pm
I think it is because fruit flies and people have genes in common They tell what kind of diseases can be curef by altering the dna of other people or giving them a special drug. Since the genes a are similar wat happens with the flies would probably happen to us
January 5th, 2009 at 10:17 pm
Scientists use Drosophila melanogaster because they are cheap, and easy to handle. Drosophila melanogaster are also quick breeders and their generations last about 2-4 weeks. Scientists are looking for a cure for Alzheimers through the study of Drosophila melanogaster and their photographic memory.
January 5th, 2009 at 10:27 pm
The Scientists use Drosophila Melanogaster in their research because it is said that fruit flies have the same cell like the humans have. And their using them to find a cure for the Alcimer Disease. And they found out that fruit flies can be smart.
January 6th, 2009 at 4:09 pm
The scientest use flies to test with genetics. When they are tested they call them fruit flys. They use flys because they cant test with humans.
January 6th, 2009 at 4:47 pm
Scientists use Drosophilla Melanogaster for their research because they want to study things that can be easily handled. Their problem is that they want to study the life cycle of a fly. So what is the life cycle of a fly and how long is each stage?
January 6th, 2009 at 4:52 pm
Well they use drosophila which are the fruit flys because they are small.
They also use these types of flys because they are easy to use and handle.
Also they can identify which are the male and female flys.
They also are easy to use because they can put enastiza to make them go to sleep when scientists want to take out the flys out of there tubes.
January 6th, 2009 at 5:00 pm

Also they can identify which are the male and female flys.
They also are easy to use because they can put enastiza to make them go to sleep when scientists want to take out the flys out of there tubes.
Well scientists are trying to find a cure for the people who cant hear out of the flys.
January 6th, 2009 at 5:13 pm
Scientists use Drosophila melanogaster for there research because they have very good long term memory because of a certain cell they have in there body. Scientists use them on questions about how they might could find a similar cell in humans so they can help cure alzheimer’s. They also use the drosophila melanogaster because they are small and easer to control then other animals.
January 6th, 2009 at 5:28 pm
They use them because their DNA is almost the same as ours(like bananas)They are trying to use them to find a soultion to altimers. They also use them to find out more about genitics.
January 6th, 2009 at 6:36 pm
Scientist are using Drosophila melanogaster for their research because they are small and easy for storage. They are also cheap and easy to afford for. Since they have a small generation time the class can see different generations of Drosophila melanogaster. They are being used to observe different genes. We use their genes because they are similar to our genes.
January 6th, 2009 at 10:41 pm
they study drosophila melanogaster on how smart they are and they are easy to handle. The questions they need to answer is that if the drosophila melanogaster can remember were to go on the tube.
January 6th, 2009 at 10:52 pm
The scientist use Drosophila Melanogasters because they are very easy to handle and there Dna is close to ours. These Drosophila Melanogasters are being used to try and help with the all timers desease because scientist said that they have good memory.
January 7th, 2009 at 11:19 am
They are easy to take care, not hurt people, and not bite. They can put them sleep for 35-40 minutes and different generally like males and females. Males are smaller round body and Females are larger round body but with little baby in her body.
January 7th, 2009 at 11:27 am
The Drosophlia Melanogaster keep like easy care do not die it, they not bite hurt to people, They are very tiny and both has male and female but male are smaller and female are large it different Drosophlia Melanogaster and Female only has lags egg baby but they are very so tiny and I can’t see it because they are very tiny but few can see one white egg.
January 7th, 2009 at 3:51 pm
I think they use Drosophila malanogaster because they want to absorb things about them like how they breed,or there shape and size. Then i think they would like to find things that is wrong with them to find a cure for it and save them for dying. If i had to ask a question it would be what was there history in life since they live only for two weeks? Also if i was a person who could answer that question i would say they live less because when they dont have the correct care they die and also if you keep them in a container you have to give them food and many other flies to breed and go through the five stages.
January 7th, 2009 at 4:50 pm
I think scientists use drosophila melanogaster because it sounds more professional. The questions that are being answered with these fly’s are. They are trying to find a cure to Alzheimer’s disease. Scientists are now conducting tests on fly’s to test there memory. Also they think if they can make you have a memory they can take away your memory to. So scientists would like to know if they can take a piece of your memory that was crucial so that you don’t have to live with it for the rest of your life.
January 7th, 2009 at 5:42 pm
Scientist use Drosophila melanogaster for their research because their not that expensive and have similar genetics as humans. Their life line is short and their easy to take care. One question the fruit flies are being used for is to answer is if they are some how related to us humans, because of their genetics. Another question is that if the flies can memorizes certain things like their past, or if they have any memory at all. One question I have is that if flies can be smart enough to finish a maze two times in-a-row(but the second time would be much faster), so I would actually have proof that flies have excellent memory like humans. Also the life cycle of a fruit fly is somehow similar to the human life cycle but theirs is shorter.
January 7th, 2009 at 5:59 pm
Scientist use Drosophila Melanogaster because they are small and have a short growing period. They are also CHEAP!!!! Scientist are trying to find a cure for alsimers since D. Menlanogaster have a fantastic memory.
January 7th, 2009 at 6:14 pm
Drosophila melanogaster are used for testing to see if there can be a treatment/pill to help elderly people with memory. They are used because they are easy to handle and can be put to sleep so they wont move.
January 7th, 2009 at 7:09 pm
Scientists use Drosophila melanogaster because they have some of the same genes we do and they are cheap and easy to breed. They are being used to find a cure for people who have Alzheimer’s Disease. They have a short life span which is good because scientists can see many generations in a short time period. This allows scientist to see the affects of changes to the fly’s genes over many lifetimes to see how the gene is formed which helps memory gain.
January 7th, 2009 at 7:21 pm
Sicentists use Drosophila melanogaster for research because their cheap. Also they are easy to maintane.They produce faster and are easier to take care of than a big animal.
January 7th, 2009 at 9:31 pm
Drosophila melanogasters are used by scientist, first to research and experiment with genectics . Drosophila melanogasters are also used in scientific research because they are cheap to by and they are easy to manage. This specises of flies in particular are being used to create a medicine that will slow down or potenualy stop the disease Alzhamers.
January 7th, 2009 at 10:22 pm
I THINK SCIENTIST USE DROSOPHILI MELANOGASTER BECAUSE THEY DON’T LIVE A LONG TIME. SCIENTIST ARE STUDY DROSOPHILI MELANOGASTER BECAUSE THEY HAVE A GOOD MEMURIES AND THAT WHY SCIENTIST ARE THINK THAT THE DROSOPHILI MELANOGASTER THEY CAN TURN THERE MEMURIES OF THAT IS WHAT THERE STUDING OF PERSON BECAUSE IF THERE IS A BAD THINK AND YOU WANT TO FORGET YOU CAN TAKE A DRUG TO FORGET.BUT YOU DON’T KNOW IF THE MEMURIES YOU FORGET AND MARYBE MORE SO THAT IS THEY SCIENTIST HAVE TO STUDY THEM MORE.THE DROSOPHILI MELANOGASTER ARE STUDY TWO BECAUSE SO PEOPLE THAT ARE OLD THEY FORGET SO THEY ARE MAKING A DRUG BECAUSE OF THE DROSOPHILI MELANOGASTER.
January 8th, 2009 at 12:20 pm
Scientists use Drosophila Melanogaster for their research because it is small and affordable. They are also easy to put to sleep, and their life span is short. The type of questions that the Drosophila Melanogaster answer help us figure out the genetics passed down from generation to generation.
January 8th, 2009 at 4:52 pm
They use them for there researches because those type of flies have the same genetics as humans. Drosophila melangaster also have babies faster. They are trying to see the different generations that they make.
January 8th, 2009 at 5:27 pm
because they inespeive and easy to put to sleep and they it dont take much to feed them. They are asking us do we know what color they eyes are and other stuff about them.
January 8th, 2009 at 7:45 pm
Scientists use Drosophilia Melanogaster for their reasearch because they are very easy to handle. One, they are very small, and don’t even cost that much to buy. Drosophilia Melanogaster is used today for diseases such as cancer. Other scientists use the flies as a cure for a disease that makes you loose your memory over a period of time, it is called alzheimer’s disease
January 9th, 2009 at 8:54 am
I think the reason scientists use Drosophilla Melanogasters ffor their research because they are smaller and easier to deal with and they have a shortlife span.I think they are being used toanswer questions like:Can Drosophilla Melanogasters cure any dieses?,And I think they are studing Drosophlla Melanogasters to see if they have the same genes as humans, and The other thing I think that scientist are using Drosphilla Melanogasters to see what would happen if they were to cross breed the flies and how would their babies respond to things and how long they will live.
January 9th, 2009 at 8:57 am
scientists did this so they could see if they would cross bridges like from different types like sipea and wild type.
January 9th, 2009 at 9:01 am
Scienctist use Fruit flys for expermints because they are chep, small and easy to put to sleep.
They are being used to study genetiics.Scienctist also use used because Males and females look very different making it quite differnet to distinguish them apart.
January 9th, 2009 at 9:03 am
Scientist uses Drosophila melanogasters in their research because they want to see if they can cross breed. And they are small and have a short life spand. They are also easy to put to sleep. Drosophila malanogaster is also small so it makes it easy for scientist to do research on them.
***** Tianna Moore*****
January 9th, 2009 at 2:11 pm
scientist use fruit flys for resarch because they are sopose to be used
for kancer. Also fruit fly’s are sopose to cure other diseases as well.
January 9th, 2009 at 2:51 pm
Scientist use Drosophila melanogaster because they are tiny and easy to see.they also not expensive and there easy to feed.They are going to be used to see if there is there a cure for altimers for old people.
January 9th, 2009 at 5:48 pm
Scientists use Drsophila Melanogastors because theis small, easy to handle, and they have a short generation period. These flies are being used to help cure arthritis. Scientists are also trying to use the flies for short memory lost.
January 9th, 2009 at 6:36 pm
I think they use it because it tells them alot of information.
They need the infor mation like eye color , body shape , habitat , food , and there genitics.They need to know the information to help the flies and try to keep them from dieing. Thats why scientist use Drosophila melanogaster.
January 10th, 2009 at 1:16 pm
The reason why scientist use is because they can be easily and they have simple genetics. They’re being used find a cure for alzheimers
January 10th, 2009 at 4:22 pm
We use these fly to see what traits they bring from ther parntes.Also to find a cure for a deise to bring people to remember tings. That is why we use dorsphila.
January 10th, 2009 at 5:37 pm
Drosophila melanogaster are used to understand the processes in humans because they have similar genetic processes. They are also used because they are easy to handle and can be put to sleep so they wont move. Drosophila melanogaster are used for testing to see if there can be a treatment/pill to help elderly people with memory.
January 10th, 2009 at 11:26 pm
I believe that the reason that scientist use “Drosophila Melanogaster” for research is because of their human characteristics, and because of their human like genes/ human genetic inheritance. These organisms are being used to answer many questions and problems. For exmaple questions on cancer, taste, sight, smelling, and hearing, and many others. So far according to many studies they have been a very good resource to use for the questions that many need answers to.
January 11th, 2009 at 10:08 am
They use Drosophila melanogaster for research is because of there small size ,ease of growing. Also a short reproduction time. The type of questions they are trying to answer is what would two type of fruit flies babies come out looking like.
January 11th, 2009 at 10:13 am

Scientists have answered many questions but there are more and the fruit fly (Drosophila melanogaster) is a key to answering many more questions. Scientists are using Drosophila melanogaster to answer questions about genetics. But why use fruit flies to study our genes? Fruit flies actually have a very similar genetic pattern to ours so people can do experiments on these cheap, easy to handle, orginisms and still have somewhat of an idea of what our genes are like. For example, if people are trying to find a cure for a sickness, you can experiment on fruit flies to find the cure. That is what makes Drosophila melanogaster perfect for scientists to research.

January 11th, 2009 at 2:20 pm
I think scientists use Drosophila Melanogaster for their research because they are small and easily handled. Well the type of question we are using for these organisms is to see their life cycle and the different generations. Others questions could be like why do the flys die so quick.
January 11th, 2009 at 2:46 pm
The reason they use Drosophila melanogaster is that they can be easily tell witch one is male and witch one is female. Another reason is that there life span is short so the people who are studying them can study many generations of them in a short time. One last reason is that there are a lot of them in life so the people studying them can easily get there hands on a number of them. What they are trying to find out is what kinds of genes are passed down to each generations and can this be able to benefit mankind (or something like that).
January 11th, 2009 at 3:08 pm
Scientist use Drosophila melanogaster’s for their research because they are so small, less expensive, and have longer generation spans. They are being used to answer questions about genetics and behavior. Also they are being researched for their offspring to see what the offspring will be like compared to their parents traits and so on from what is passed down.
January 11th, 2009 at 3:12 pm
Scienist use Drosophila melanogasters for their research because they can learn about genes faster through these flies. They also use these flies because they are cheap to maintain and easy to study once they are put to sleep. The last reason why scientist use Drosophila melanogasters because they have a 4 week life cycle which makes it easier for them to see the different traits they receive from their parents, grandparents, and etc. These flies are bein used to answer quetions such as why do people get certain traits from their mom and not from their dad or from their dad and not from their mom.
January 11th, 2009 at 5:58 pm
Sicentist use fruit flies because they are eaiser to use like being able to tell the diffrence between male and female eaiser.They are smaller and easy to handle. They breed easy. The questions being ask is how will the flies look when being breed with another speices. Yes they are by looking at the eye color and the color of the fly dat is answering the questions.
January 11th, 2009 at 7:49 pm
Because it is small, easy to put asleep, easy to take care of and they are safe. We are asking questions like will there children look like the parents and if so which one mom or dad or both. And what will happen if a mutated fly has babies with a non-mutated fly how will the babies turn out.
January 11th, 2009 at 8:11 pm
scientists use Drosophila melanogaster because they have a short generation and they are cheap.
Drosophila melanogaster are use to study genetics and Alzheimer.
January 11th, 2009 at 8:30 pm
Scientist use Dropsophila melanogasters because they have a short life span of 2 weeks. Their are testing the flies in a maze to make the flies have long term memory. And to also see if they can create a pill to cure memory loss.
January 11th, 2009 at 8:59 pm
The reason scientists use D. Melanogaster is beause they study the genes of the fly’s to see what genes do what so we can use that to our advantage. The fly’s are studied because there genetics are much like our own, except ours are just a bit more complicated. Scientists currently are studying the fly’s genetics to figure out how to stop long term memory or help to stop it. In the video we saw the scientists turned off the fly’s memory gene, and obsevred what happened compare to what the fly’s memory gene was always on. a regular fly took ten times to remember something but the flys with the gene always turned on took 1 try.
January 11th, 2009 at 9:03 pm
Scientists use Drosophila Melanogaster because they are easy to care for and have very similar DNA of that of humans. They are used to study genetics. They are a great substitute for humans so that we are not used as test subjects.
January 11th, 2009 at 9:27 pm
Scientist use Drosophila Melanogasters for their research, because they are small and easy to control. They also use them because they have a quick life span, and they can observe more generations faster then they can with other living things. The Drosophila Melanogasters are being used to study genetics. Such as how strong certain genes are, and how certain genes affect your life.
January 11th, 2009 at 10:28 pm
Scientists use Drosophila Melanogaster for their research because they are cheap, easy to handle, small, and their generations are short. Scientists are researching them to see if they can come up with a cure for Old Timers. Also to see if they can make people forget certain things or remeber certain things.
January 11th, 2009 at 11:13 pm
Scientist use drosophila melanogaster for their research because nthey they think that they can use it to cure memory. What scientist ask is can drosophila melanogaster fight momoery lost or will it not work. the reason for this is because older people fromtheir 70’s and up start to lose their memory and soon as the years go by it their memory of everything ends up completely gone, so that’s why scientist are trying to find a cure for memory lost.
January 12th, 2009 at 7:48 am
they use Drosophila melanogaster to find out more about genetics.the Drosophila melanogaster are good to use because they are small they can live with little food.they can live in small areas.
January 12th, 2009 at 8:42 am
I think scientists use the friut fly for their research because it is small and easy to care for. Also doesn’t need much attention, the flies are being used to cure a disease that elderly people have.
January 12th, 2009 at 8:43 am
Scientist use Drosophilas because the equipment is cheap and they are easy to handle. What will happen when you mix 2 different types of Drosophilas together. They are also being studied by mixing the gene pool.
January 12th, 2009 at 8:45 am
Their small and easy to use especially for experimenting. From what I noticed their easily to handle and they don’t bite. These mysterious fruit flies love rotten fruits of any kind.
January 12th, 2009 at 10:01 am
becauce flyes are more smaller then other anamoles and they wan cas iny pramblems and they use less space
January 12th, 2009 at 11:01 am
the flies are use to study how they make different babies and how they are the same as their grandparents. Drosophila melanogaster are flies that scientist study, they study this tipe of fly because they are easy to work with. the flies wont harm you in any way, they are easy to put to sleep and they can look at them really close so they can study them.
January 12th, 2009 at 11:05 am
These flies are being used to cure this illness that elders get ,They forget their memmories. Scientests are trying to find a cure to bring there memories back. These flies are used to invistagate on how genetics work.
January 12th, 2009 at 11:07 am
scientist use these flies for illness and geneictics. they are studying there life cycle. there are helpful.
January 12th, 2009 at 11:08 am
The scientist don’t what to study on other people and it hard to combience someone to study them. The Drosophila melanogaster is easy to study and it cost less than any other animals. the Drosophila melanogaster has a short time of a life cycle and whe can study them in 14 days.
January 12th, 2009 at 4:01 pm
Scientist’s ude D. Melanogaster’s to reasearch on them because they’re cheap and they don’t need a whole lot of attention to live. They are being used to answer some scientific questions.
January 12th, 2009 at 4:18 pm
The scientists use the fruit fly because they are quick at reproducing. I say that because it takes them no longer than two weeks to reproduce and die for generations. We are finding the mutations and what are the generations like and how are they changing.
January 12th, 2009 at 5:24 pm
They use in their research to see why it helps for alzheimers. Their problems that they are using them for are for alzheimers.
January 12th, 2009 at 10:25 pm
1. Because, Drosophila melanogasters past down genes from the past flies. Like humans do.
2. How genes are past down from one set of familys to another.
January 13th, 2009 at 7:11 am
Scientist use Drosophila Melenogaster for their research because they have a short life span and they breed and produce offspring a lot. One way the scientist are using these organisms to try to find a way to cure alzheimers. Another way is to learn about how genes are passed on from parents to offspring.
January 13th, 2009 at 8:43 am
scienntists use Drosophila melanogaster because they are small and easy to handle,and u can put them to sleep with acemical. This living organizam is used to study the genetics and its not easy to do it in a human body so they tdo it with a fly(Drosophila melanogaster ).

Scientists use Drosophila melanogasters because they are verysmall and easy to handle. They are easy to keep. Scientists are trying to see if they can make medicine out of the flies.
January 13th, 2009 at 8:53 am
They use Drosophila melanogaster to study, becuses thay are cheap. Also easy to mantane. The Drosophila melanogaster is being studyed becuses thay are tring to find a cure for alsimers in old people. Thay are using ther memory geans to find a drug that can make your memory better. Also a drug that can make you forget bad memorys.
January 13th, 2009 at 8:58 am
Drosophila Melanogaster is being used for trying to find the cure for ashimer. Scientist have discover that fruit flys (Drosophila melanogaster) have a gene that controls the fruit fly’s memory. If the scientist could find the gene that controls a person’s memory. scientist could probibly find a cure for ashimer.
January 13th, 2009 at 8:59 am
They use these flies to to cure alstimer.They have quetions they have are can you use the flies to see how genes are to tranferred from parents to th e children. Can they actual you cure cure alstimer with the Drosophila melanogasters
January 13th, 2009 at 9:00 am
Drosophila Melanogaster is being used for trying to find the cure for ashimer. Scientist have discover that fruit flys (Drosophila melanogaster) have a gene that controls the fruit fly’s memory. If the scientist could find the gene that controls a person’s memory. scientist could probibly find a cure for ashimer. There are three types of flys.
January 13th, 2009 at 9:10 am
they use them because they are easy to get and breed fast. they are trying to find out about maybe controlling or altering genetics.
