[Homework]2015-02-07 英国议会下院通过“三亲育子”技术法案

If you are confused by three-parent embryos, you've come to the right place. This is my kitchen lab. The eggs here are somewhat larger. But the principle is the same and allows me to demonstrate what scientists hope to do with humans.                                                   
Inside the egg cores are two bits. The egg yolk contains the nuclears, in there are thousands of genes that make a chicken a chicken. In the egg white are the mitochondria which make energy for the cell. They too contain a small number of genes. The problem is this egg come from Henry Ater, a very sick hen. Her genes and her mitochondria are defected so she has a disease of the mitochondria. So what scientists want to do is to separate her egg. They want to get rid of the egg white with these defective mitochondria and they want to keep the egg yolk with her healthy genes, her healthy nuclears. They also have a donate egg. Now both parts of that are healthy. There's no problem with that egg. But they also want to go through the same process, so they remove the donated yolk or these nuclears. They put that to one side. And the keep the healthy egg white, they want that. And they add to it Henry Ater's nuclears, with all her genes to make him a new egg. And believe me for a few weeks time that could turn in to a chick, it would be healthy. It would contain Henry Ater's genes but not her disease.
