When bacteria survive a viral attack, they incorporate snippets of the virus's DNA into their own genomes.

当细菌在病毒的攻击下存活下来后，它们将病毒的DNA片段合并到自己的基因组中。

There are two types of herpes simplex viruses —HSV1 and HSV2 —both of which are part of a larger family of enveloped double-stranded DNA viruses: the herpesviridae family.

单纯疱疹病毒有两种血清型：HSV-1和HSV-2，两者都归属于一类更大的、有包膜的双链DNA病毒家族：疱疹病毒家族。

So David, what you're describing is how these virus hunters actually try to get the DNA from bats that contain the virus DNA, but I'm curious about why do virus hunters generally do this sort of work?

大卫，你刚刚描述的是，这些病毒猎人如何从含有病毒 DNA 的蝙蝠身上获取 DNA，但我很好奇为什么病毒猎人愿意做这种工作？

So when a bacterium encounters a virus for the first time, it can store a small snippet of that virus's DNA for use as a program to direct the CRISPR scissors to cut that viral DNA sequence during a future infection.

因此，当一个细菌第一次遇到病毒时，它可以存储一小段病毒的DNA，作为一个程序来指导CRISPR剪刀在未来的感染过程中切断病毒的DNA序列。
