The two main classes are RNA viruses (see retrovirus) and DNA viruses.

主要的二类是核糖核酸病毒和去氧核糖核酸病毒。

As the reverse transcriptase is lack of effective function of proofreading the bases, the HBV genome is easier to mutate than other DNA viruses.

HBV复制过程中要经过逆转录，由于逆转录酶缺乏有效的碱基校对功能，故hbv基因组比一般dna病毒易发生变异。

I talked about just not using viruses but using plasmid DNA together with lipids and that's another strategy for gene therapy.

这一部分我们不仅讲了病毒的应用,也讲了利用脂质体包裹的质粒DNA,基因治疗还有其它的策略

We have techniques of recombinant DNA, and those can be used to produce either modified viruses, we'll talk about that.

我们拥有重组DNA技术,它可以用来生产任一种减毒病毒,这个以后会再讲

Dr Venter's was the real McCoy: when he put the viral DNA into host cells they started to spit out new viruses just as self-destructively as cells infected with the natural Phi-X174.

DNA, which the host cell then unwittingly uses to make more viruses.
