I want you to look at this picture, read the little bit about gene - control of gene expression - that's in the book, know that it's a big topic, that we're not going to talk about it except we're going to talk about some examples where control of gene expression can be exploited in order to treat diseases, for example. So I'll see you on Thursday.

所以我希望你能看一下这张图,读一些,教材里基因调控的章节,这是个很大的话题,我们不会进一步深入去探讨,但一些基因调控,用以治疗疾病的例子,我们可能还会在之后的课程中讲到,那我们周四见了
