提高英语听力能力 找对方法很重要!
homework===If you are confused by three parent embryos, you've come to the right place. This is my kitchen lab. The eggs here are some of larger but the principal is same and allows me to demonstrate scientists hope to do with humans. Inside the egg cores are the two bits. The egg yolk contains the nuclears in there are thousands of genes that make a chicken a chicken. In the... are the mitochondria which make energy for the cell too container small number of genes. The problem is this egg comes from Henry Ater a very sick hen. Her genes and her mitochondria are defective so she has a disease of the mitochondria. So what scientists want to do is to seperate her egg. They want to get rid of the egg whites with these defective mitochondria and want to keep the egg yolk with her healthy genes her healthy nuclears. They also have a donor egg now both parts of that are healthy. There is no problem with that egg. But they also want to go through the same process. So they remove the donated yolk or this nuclears they put that to one side and they keep the healthy egg white, they want that. And they add to it Henry Ater's nuclears with all her genes to make a new egg. And believe me for the few weeks time that could turn in a chick it 'll be healthy, it'll contain Henry Ater's genes but not her disease.
