They differentiate, they make many copies of themselves - I'm sorry they proliferate, they make many copies of themselves, and then they differentiate into antibody production machines.

它们开始分化,再制造很多自身的拷贝,对不起应该是先扩增,扩增出很多自身的拷贝,然后分化成为制造抗体的机器

It's really been a powerful tool in molecular biology because I might have a very small copy of a gene that I'm interested in and I can make enough copies that I can start to do something else with it.

这确实是分子生物学的一项利器,因为我可能只有,很少量的感兴趣的基因拷贝,而我可以马上制造出足够数量的复制品,能使我用作其他用途

So the process of cloning DNA is taking a few strands of DNA of a gene that you're interested in and making many copies of them, that's cloning,you like to make identical copies.

所以DNA克隆的过程,就是用你所感兴趣的,基因的一些DNA链,来得到更多它们的拷贝,这就是克隆,复制出相同的拷贝
