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

它功效和抗逆转病毒药物似，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.

如果存病毒RNA，引物便会与RNA单链结合，之后逆转录酶将会合成一条互补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.

我们体内有一种最为常见基因——一种被称为逆转录酶质，据知它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“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互补双链。

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操作步骤是：首先将鼻咽拭子部分样本加入到含有逆转录酶、核苷酸和引物溶液中，其中引物将与SARS-CoV-2病毒目标序列互补。
