We'll talk more about promoters as they go on, for now let's just assume that we have a promoter that works in this particular cell.

我们以后还会谈到更多有关启动子的知识,而现在就假设这个,特定的宿主细胞里有个启动子

We're going to come back and talk about the action potential a little bit more when we talk about how the heart works, because the heart when its contracting, the muscle cells also use action potentials to initiate contraction.

我们讲心脏工作原理时,会回头再多讨论一点动作电位,因为心脏收缩时,肌肉细胞也利用动作电位来启动收缩

Now when we put insulin in this place behind the right promoter, the cell thinks that it still has the lacZ gene present which it needs for its metabolism.

现在我们把胰岛素基因,放在正确的启动子后面,宿主细胞就会认为,它仍然有新陈代谢所需的lacZ基因
