Those two examples I just gave you, one had to directly inject a gene containing vector into the pronucleus of a fertilized egg and you don't have that opportunity in adults.

在我刚给出的两个例子里,一个必须得将带有目的基因的载体,直接注射到受精卵的原核中,这在成年人身上行不通

The cell is a fertilized egg, so you take a fertilized egg and you directly inject plasma DNA into the pronucleus, into one of the pronucleus--pronuclei.

供试细胞是受精卵,当你获得一枚受精卵,可以直接将胞质DNA注射到,它的一个原核中

In this case, if everything goes right, you inject the DNA into the pronucleus, you implant this fertilized egg into a foster mother, the mother gives birth to offspring, it develops and when it develops this foreign DNA is in the offspring.

如此一来,如果一切顺利,DNA成功注射进原核,受精卵成功植入代孕母亲,成功的孕育了后代,后代健健康康的长大,目的基因就成功的整合进了后代的基因组
