Fish are rich in Omega-3 Fats
But what if you don't like fish? Read Moving Good Fats from Fish to Mice. Why are Omega 3 Fats good for you? What is genetic engineering? How are scientists making beef and chicken better for you? Don't forget to explain how this relates to protein synthesis and transformation.
Scientists are saying that they are able to place omega-3, which is in fish, inside of mice to see if it makes them healthier and adds muscle. The scientists' goal is to put the special omega-6 into cows and chickens to make humans healthier. Cows will have richer milk, and chickens will have better meat.
Omega 3 fats are good for people because it helps make your heart healthier. Unlike omega 6, which does the opposite of omega 3. Genetic engineering is the ability to change an organism's DNA using lab techniques. To make beef and chicken better for health, scientists figured out that worms can change omega 6 fats to omega 3 fats. Therefore, scientists put the omega 6 from the worm into mice. After 8 weeks, the results showed that the mice muscle tissues had more omega 3 than a normal rat. This is an example of transformation because the omega 6 fats are changed to omega 3. Transformation is when a cell takes up genetic material. The change from omega and transformation make a good difference for the human body.
Fish is very good for your heart, unlike poultry and red meats. Red meats and poultry contain a fat called omega-6. Fish contains omega-3. Omega-3 helps your heart, unlike omega-6, which has the opposite affect. Worms, called nematodes, contain a gene that can convert omega-6 into omega-3. Scientists hope to use this and put it into cows and chickens to make the meat and their products as healthy as eating a fish. This relates to class because of the genetic engineering aspect.
This is a great feat. I, myself don't like fish. I think it is tasteless and triggers my gag reflex, so unfortunately i don't get much omega-3. Now, though with this discovery I could get my omega-3. this relates to our unit in that it changes the DNA in the muscle cells to produce omega-3 instead of bad omega-6. this would a great achievement and for the heath of the world.
This article describes how scientists have identified a gene in nematodes that converts Omega 6 fatty acids into Omega 3 fatty acids. Omega 6 fat is bad for your heart, while Omega 3 fat is good for it. Scientists subsequently placed this gene into mice which gave out amazing results; the treated mice had less Omega 6 than Omega 3, while the average mouse has much more Omega 6 than 3. These scientists engineered the genetic data of the mice so that they had certain traits: in this case, they had proteins which converted Omega 6 into Omega 3. If scientists are able to implant this helpful gene into poultry and beef, these meat products will be much healthier. After having their genetic code altered, the cows and chicken would synthesize proteins which they normally do not synthesize.
In my biology class I am learning about genes and fats. This article is about a worm gene that converts omega 6 fats to omega 3 fats which are healthier for you. Fish have lots of omega 3 fats but some people do not like the taste of seafood. Some scientists have figured out how to take these special genes from worms and plant them into other foods such as cow meat, chicken, cheese, etc. They took these genes and planted them into mice as an experiment. After this experiment the mice had more omega 3 fat than omega 6 fat. Mice usually have more omega 6 fats rather than omega 3 fats.
Omega 3 fats are good for you because they make you healthier. Genetic engineering is a process or act that scientists can perform to redesign the genome of a cell. This can be done by inserting different DNA into the cell. In this case, if scientists insert the gene these nematodes have for the omega 3 into other organisms such as cows and chickens, then the cows and chickens should be able to use the same gene. This would increase the amount of omega 3 in these animals and therefore, make it much healthier for humans. This is a type of transformation because the scientists redesign the gene for it to produce the same qualities in a different organism.
Omega 3 Fats are good for you because they make your heart healthier. Researchers and scientists found out that nematodes have this special gene that turns omega 6, into omega 3, and they are planning to be placing them in cows and chickens. In what is going on, the genes are being genetically engineered. It's also a part of transformation because the cell is being modified.
Omega 3 Fats are good for you as they make your heart healthier rather then hurting your heart as most fats do. The scientists this article discusses are using genetic engineering (the using scientific procedures to alter the hereditary traits of an organism, or population) to make beef and chicken filled with much more omega 3 than normal, and thus better for you. This relates to protein synthesis as genes can’t do anything by themselves, they would have to go through protein synthesis to create an enzyme to break down the fat. This experiment also wouldn’t have worked without transformation. If the mouse couldn’t use this gene nothing would have happened.
Amazingly, worms known as nematodes have a gene that converts omega-6 fats into omega-3 fats. A group of researchers from the Massachusetts General Hospital in Boston wanted to see if they could tap into the power of this particular gene. So, they took it out of some worms and put it into some mice. The experimental mice were then raised on the same diet as a group of normal mice.
After 8 weeks, muscle tissue from the experimental mice had more omega-3 fat than omega-6 fat. This was a huge improvement. Normal mice have far more omega-6 fat than omega-3 fat.
Researchers hope eventually to be able to put this worm gene into cows and chickens. The resulting milk, beef, and eggs would then be rich in good fats and as healthy for your heart as a slab of grilled salmon.
Don't be surprised if worm genes someday wind up enriching your milk or yogurt. Your taste buds won't notice the difference, but your heart will reap the rewards.
Omega-3 fats, fish, are important to us because it helps our hearts, while omega-6, found in red meats, does the opposite. Scentists have found out that worm genes can make omega-6 into omega-3. Researchers will evenually but this worm gene into cows and other mammals, making our dairy foods rich in omega-3. Genetic Engineering is the ability to change an organism's DNA using lab techniques. This relates to Protein Systhesis in some ways. The DNA of the orginial product are replaced or subsituted by the worm genes, making a mutation, resulting in a new product.
