This works similar to antiretroviral drugs by blocking the enzyme reverse transcriptase.

它的功效和抗逆转病毒药物相似，用来阻挡逆转录酶。

If the viral RNA is present, the primers attach to the RNA strand and then reverse transcriptase synthesizes a cDNA strand.

如果存在相关病毒RNA，引物便会与RNA单链结合，之后逆转录酶将会合成补DNA链。

One of the commonest genes we have is for a protein called reverse transcriptase, which has no known beneficial function in human beings at all.

体内有种最为常见的基因——种被称为逆转录酶的蛋白质，据知它在人体内根本不起任何好作用。

The " retro" part of retrovirus isn't referring to its style, but refers to it needing to use an enzyme called reverse transcriptase to transcribe a complementary double-stranded piece of " proviral" DNA.

逆转录病毒“retrovirus”中的“retro”并不是指复古风格，而是指它需要逆转录酶合成前病毒DNA的补双链。

To perform RT-PCR, some of the extracted sample from the nasopharyngeal swab is added to a solution containing an enzyme called reverse transcriptase, nucleotides and primers that are complimentary to a specific SARS-CoV-2 target sequence.

RT-PCR的操作步骤是：首先将鼻咽拭子的部分样本加入到含有逆转录酶、核苷酸和引物的溶液中，其中的引物将与SARS-CoV-2病毒的目标序列补。
