They basically make many, many copies of their DNA and they make all of their viral proteins and they assemble into new viral units.

它们会生成不计其数的病毒基因拷贝,并翻译生成病毒蛋白,组装成新的病毒单位

Because they've made many copies of their genome and they've made all the proteins that are necessary to - for assembly of a new virus, then this cell can make many new viruses.

因为病毒制造了大量病毒基因组的拷贝,和所有,新病毒组装所需的蛋白质,所以这个细胞就有能力制造大量新的病毒

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

How did we put our gene fragments into this plasmid DNA in order to make multiple copies of it, or to clone the gene?

如何把基因片段整合到质粒DNA上,来获得大量拷贝,或者说来克隆基因呢

When you think about a gene or a transcript, the messenger RNA copy of a gene, you know that for every sequence of a nucleic acid there's a complimentary sequence.

当你们考虑一段基因或者一个,转录一段基因的mRNA拷贝,你们知道每个核酸序列,都有互补序列

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
