And you'll find in the end that recursion is a feature of a language, it allows you to map some very obvious concepts like the phonebook tearing in half and half and half and half to actual code without it using some arbitrary human contrived framework like a for loop or a while loop which are much more stilted mechanisms.
最后你会发现递归是某种语言的一种特征,你可以用它将一些非常明显的思想,比如将电话簿划分为一半又一半,映射为实际代码，而不必使用那些人为框架,像for循环，while循环之类的,那是很呆板的机制。

Well let's talk about some mechanisms for using this and I'll start with a simple example of how one can detect a gene in a fluid, in a blood sample for example, where that gene is unknown.

Again, the point today is not for you to understand in detail all these mechanisms but to understand how those basic concepts we talked about last time, basic concepts of cell communication if arranged in the right kinds of ways can lead to complex outcomes.

Now the nice thing about this is that the degradation mechanisms seem to persist for some period of time, beyond the time at which you deliver the double stranded RNA; whereas, obviously, this mechanism here is only going to exist for as long as the anti-sense sequence is present.
而好消息是降解过程会持续一段时间,比你转入双链RNA的时间要长,但是,这种机制只会在,有反义链的时候发挥作用
