这一前沿工程使用了一种“猎枪”方法。首先分离出一个DNA链，之后通过化学反应使它复制自身上百万次。

This pioneering project used a "shotgun" approach, which first isolates a DNA strand and forces it to copy itself millions of times over in a chemical reaction.

新的文件，能够更新在2003年出版的联合空中作战理论，该文件称，当数据链路在战斗中失败，那么可以很难使无人机返回基地。

The new document, which updates joint air operations doctrine published in 2003, says that when data links fail in combat it can be tough to get a UAV back to its base.

迈克尔-波特在其1985年出版的“竞争优势：-营造并保持最佳表现”的第二章，首次将价值链作为一种商业理念提出。

The value chain was first developed as a business idea in the second chapter of “Competitive Advantage: Creating and Sustaining Superior Performance” by Michael Porter, first published in 1985.

Let's check it out. I've written a little bit of a test script here, so if we test cell sort, and I've written this so that it's going to print out what the list is at the end of each round, OK.

我们来检查检查，我写了一个小测试脚本,我写这个脚本来测试单元排序，它能够打印出每一轮结束后,链表的是什么样子的。

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

If I told you that a DNA sequence went 5' to 3' you could draw the whole thing referring back to these notes, right?

如果我告诉你一个DNA链从5'到3',是AGTG,你就可以,画出它的整个结构
