[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 parients, you come to the right place. This is my chicken lab. The eggs here somewhat larger but the principles are the same and allows me to demonstrate what scientists hope to do with humans.Inside the egg cores are the two bits. The egg yolk contains nucleus in there are thousands of genes that make a chicken a chicken. In the egg white are mitochondria which make energy for shell. The two contain a small number of genes. The problem is this egg comes for ..., a very sick hen. Her genes and mitochondria are defeted so she has a disease of mitichondria. So what scientists want to do is to seperate her egg, they want to get rid of egg white with defeted mitochondia, and want to keep the egg yolk with her health genes and health nucleus. They also have a donated egg, both parts of that are healthy. There are no problem with that egg. But the also want to go through the same process. So they remove the donated yolk with this nucleus. They put that one side, and they keep the healthy egg white.And they add to it,...nucleus with all her genes to make a new egg.And believe me for the few weeks time that can turn into a chick. It would be health. It would contain ...genes but not her disease.
