Run merge sort on those. By induction, if it does the right thing, I'm going to get back two lists, and I'm going to then merge Them together. Notice what I'm going to do.

The reason that 3' is important is that when you polymerize two nucleotides together and a third nucleotide, and a fourth nucleotide, when you polymerize nucleotides together they get polymerized, the phosphate of one gets linked to the 3' carbon of another.
'碳部位重要是因为,当你把两个核苷酸聚合在一起,然后再聚合第三个,第四个的时候,核苷酸在聚合时,磷酸基与另外一个戊糖的3'碳部位连接

All right. So you probably read in the book that the bassoon is a double reed instrument, and so just to show you what that looks like-- You've probably seen it but if you haven't, two pieces of wood vibrate together when I blow through them.

I mean, you should not imagine when I say slaves--just take out of your mind the plantations of the old South, because when you only have one or two slaves, the master is working right alongside them, doing exactly the same work that they are doing, and also instructing them and telling them what's what.
我的意思是,当我们提到奴隶的时候,大家不要想当然地联想到南部种植园,因为当你只有一两个奴隶时,奴隶主必须要和奴隶一起劳作,做着和奴隶一样的农活,并且不断告诉他们要做什么

And what we end up forming is a molecular orbital, because as we bring these two atomic orbitals close together, the part between them, that wave function, constructively interferes such that in our molecular orbital, we actually have a lot of wave function in between the two nuclei.

-
So, last time I gave a reading of the creation accounts that are in Genesis 1 to 3. These are two very different stories but their placement side by side suggests the possibility of a joint reading. Nevertheless they are very different in character and today I want to focus in on the second creation story.

When these two merges are done, we're basically at a stage in that branch where we can now merge those two together, which gives us that, and it goes through the rest of it.
拿到从那边得到的第二个子列表，这是一个基本情况,合并它，当这两个合并完成后，我们基本到了该分支阶段，这里我们可以把两个合并在一起。

-
And since we have two bars that are together like this, once they're both loaded up with electrons there's going to be negative charges that repel, so the electrons will want to get as far away as possible, and they're on their slow way to doing that, to getting as far away from each other as possible.
因为我们有两个棒像这样在一起，一旦它们加载了电子,就会因为有负电荷而排斥，所以这些电子就会,互相离开的尽可能远，它们的这个过程很慢，离开的尽可能远。
