This brought in their writing skills. After we talk about all of them, we will write the numbers down - now this is three and two more - before we even tell them the plus sign, you know,how to join things together."

The goal of that was to take for a typical human, or for a typical - in the case of the human genome project maybe you're looking at fruit flies, you want to look at all the DNA in a fruit fly, but to look at the sequence of base pairs that makes up human DNA and write them all out; we'll talk about that later.

这个计划的目的是,建立一个有代表性人类的基因顺序,或者说是典型的人类基因组,就人类基因组计划来说,或许你在研究果蝇,你想观察果蝇内的所有DNA,而人类基因组计划是观察组成人类的,DNA的碱基对顺序并且将它们记录下来,我们不久之后会讨论这些内容
