转录酶

The RNA polymerase is an essential enzyme that synthesizes DNA by catalyzing the transfer of RNA nucleotides onto a growing strand, this process is called transcriptase activity."
RNA聚合酶是一种关键酶，通过催化RNA核苷酸转移到新合成链上，生成DNA，这就是转录酶活性。
Transcriptases are involved in the conversion of pre-mRNA into mature mRNA during gene expression.
转录酶参与将前体mRNA转化为成熟mRNA的基因表达过程。
In some viruses, the viral RNA genome is directly translated into proteins without the need for cellular transcriptases.
在某些病毒中，病毒RNA基因组可以直接被翻译成蛋白质，无需细胞内的转录酶。
The reverse transcriptase enzyme is used in PCR (polymerase chain reaction) to convert DNA to RNA.
反转录酶在PCR（聚合酶链反应）中用于将DNA转化为RNA。
RNA editing, a form of post-transcriptional modification, involves the action of specific transcriptases on existing RNA molecules."
