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.

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 copying is quite different from the way cells copy strands of DNA or humans copy memes.

这种复制与细胞DNA链的复制或者人类对媒母的复制大不相同。

Each messenger is an edited copy of one strand of the DNA double helix.

每个信使都是DNA双螺旋中一个单链的复制品。

It's called cDNA or complimentary DNA to indicate that it's a copy, a complimentary copy of the messenger RNA.

它叫cDNA或者互补DNA,意味着它是一个拷贝,一个信使RNA反转录得出的DNA拷贝

Transcription just means making a single stranded RNA copy of a sequence of base pairs in a DNA.

转录的过程就是从一段DNA碱基序列中,复制出一段单链RNA

Before, we talked about how do you know what messenger RNA to make, how do you know what RNA to copy from a DNA template?

在之前的课上,我们说到如何判断mRNA的具体序列,如何判断RNA从DNA模板复制了什么

The theory is that big differences come from the way in which certain RNA molecules copy DNA sequences into proteins.

The DNA had been discovered using a new technique called "low copy number DNA".
