scientists are starting to mix DNA of humans to other animals. Chines scientist took human DNA and mixed with a rabbit in an egg. this project was successful and was the first of its kind. After that they let the embryo mature the destroyed them and took the stem cells.
At stanford they are going to insert DNA into a mouse for it to grow a human brain.
Scientists think that by putting DNA in other animals from humans they can create spare parts for humans. another reason is to test the effects of certain drugs on people threw animals. I don't think it is right to do this because you are in a way torturing animals. I think it isn't right to do what is against nature. It's nature for humans to eat animals but not to be a part of them.
In some ways it is helpful like the getting spare body parts to replace others. I would only think it to be fare to do this if there is a young person who could die without that body part could get one.
There are also unethical reasons why these things are not popular. The United states has nothing against this. I think there should be. Do you think that the use of human DNA in animals is right?
I think it should be animals like mice and nothing else in my opinion
