Well let's see. My fall back is, I could just do linear search, walk down the list one at a time, just comparing those things. OK. So that's sort of my base. But what if I wanted, you know, how do I want to get to that sorted list? All right?

我只能做线性搜索了,一次遍历一遍列表，一个一个比较，但如果我想要,那怎样得到有序的列表呢？,现在的一个问题是，我们排序之前？

I just give you one of those, right, because you could write down the other one because you know the other complimentary sequence from base pairing?

我只写了一条链的序列,因为你们能够写出另一条,因为你们根据碱基配对,就能推测出互补链的序列

You know that messenger RNA is read in three base units called codons, and so this particular piece of messenger RNA is drawn in this cartoon in three base pair units.

RNA是按每三个碱基组成一个密码子,进行翻译的,在这幅动画中所画的mRNA,就是按三个碱基一组的方式来描绘的

Well you do that by this Watson-Crick base pairing, so I know if I have I know what messenger RNA to make from that because I have to satisfy these base pairing rules.

依据的是沃森克里克碱基互补配对原则,如果给我一个ACGCGA的序列,就能知道转录出的mRNA会是什么,因为我必须满足碱基配对原则
