Now most diabetics take human insulin made, not in humans, but made in micro-organisms that are growing in a manufacturing facility.
而现在,多数糖尿病患者用人的胰岛素,不是来自人体,而是来自工厂的微生物车间
Say we've got a human gene that we want to make and let's say it's the human gene for insulin that we want to produce now.
假设我们想合成出一个人类的基因,假设现在我们想合成的,是人类的胰岛素基因
If I want to clone a gene from a human, if I want to clone the gene for human isulin, mean make many copies of the gene that's responsible for making insulin, I need to know whether there are introns there or not.
如果我想要从一个人类个体克隆基因,如果我想要克隆人类胰岛素基因,亦即我要把负责生成胰岛素的基因,复制许多个副本,我就得要知道哪些是内含子,哪些不是
One way I could try to find the gene for human insulin is to take any cells from any of us, skin cells let's say, and I could identify where on the chromosomal DNA that insulin is likely to occur.
我能找到胰岛素基因的一个方法,是从任意一个人身上任意取一些细胞,比如说皮肤细胞,并且我知道胰岛素基因,可能出现在染色体DNA的哪一部分
