DNA viruses like monkeypox generally do not rapidly mutate like COVID-19 does.

像猴痘这样的DNA病毒通常不会像新冠病毒那样快速变异。

Varicella zoster virus is a double-stranded DNA virus, protected by a protein coat called capsid, which is enveloped in a lipid membrane.

水痘带状疱疹病毒是双链DNA病毒，被一种叫衣壳的蛋白质包膜保护，而它又被脂质层包裹。

Now it turns out that the spacers in CRISPR locations are kind of a historical record of DNA viruses that have previously infected the host.

现在证明CRISPR位点上的间隔序列是早先感染过宿主的DNA病毒留下的一种历史记录。

In general, RNA viruses don't have a proofreading mechanism, whereas DNA viruses do.

一般来说，RNA病毒没有校对机制，而D​​NA病毒有。

Coronaviruses store their genes on RNA. All viruses are either RNA viruses or DNA viruses.

冠状病毒将其基因存储在 RNA 上。所有病毒要么是RNA病毒，要么是DNA病毒。

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。

The snot is rich with fresh DNA, viruses and bacteria, and is collected by a drone that hovers over the blowholes of humpback whales

鼻涕里富含新鲜的DNA（脱氧核糖核酸）、病毒、细菌。鼻涕是由无人机收集的。无人机就盘旋在座头鲸上方的气孔处。

All right, as a quick recap, human herpesvirus 8 is a double-stranded DNA virus which causes a type of cancer that most commonly occurs in AIDS patients, called Kaposi's sarcoma.

得！快速回顾一下：人类疱疹病毒8型（HHV-8）会引发一种主要出现在艾滋病患者中的癌症，称作卡波西肉瘤。

In DNA viruses, the viral DNA enters the nucleus and uses the host's DNA polymerase to create more copies of itself as well as viral mRNA that gets translated into viral protein.

在DNA病毒中，病毒DNA进入细胞核利用宿主的DNA聚合酶完成自我复制，以及将病毒mRNA翻译成病毒蛋白质。

So when a DNA virus gets into a host cell, certain fragments of it called Protospacers are incorporated into the host's genome, becoming the spacers in CRISPR locations.

当DNA病毒进入宿主细胞时，其被称作" 原间隔序列" 的特定片段会被整合进入宿主基因组变成CRISPR位点上的间隔序列。

RNA polymerases are more likely to make copying errors than DNA polymerases and therefore often make mistakes during transcription, this is why mutations in RNA viruses occur more frequently than in DNA viruses.

RNA聚合酶在复制时比DNA聚合酶更容易产生错误，因此在转录过程中经常出错，也就是为什么RNA病毒的突变比DNA病毒发生得更频繁。

Human herpesvirus 8 is a large double stranded linear DNA virus surrounded by an icosahedral capsid, which is a spherical protein shell made up of 20 equilateral triangular faces.

人类疱疹病毒8型是种巨大的双链DNA病毒，其外由一个二十面体的衣壳包围，其衣壳是由20个等边三角形组成的球状蛋白壳。

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？
