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。

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。

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。

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。

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。

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。

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。

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。
