1.I see the polymerase and the enzymes and so forth.

6.Scientists then apply the polymerase chain reaction or PCR, which uses artificial DNA strands called universal primers.

接着科学家们应聚合酶链式反应，简称 PCR，使一种被称为通引物的人工合成 DNA 链。

7.Polymerase chain reaction, or PCR, might be used to find Specific causes like HIV, enterovirus, HSV, or tuberculosis.

聚合酶链式反应，或PCR，可能被来筛查出特定病因，比如HIV、肠道病毒、HSV、肺结核病毒。

8.Taq polymerase is used to amplify the cDNA through denaturation, annealing and extension steps.

Taq聚合酶通过变性、退火、延伸步骤于扩增cDNA。

9.In the nucleus, the enzyme RNA polymerase unwinds and unzips the two strands of DNA that contain the protein-making gene.

在细胞核中，RNA 聚合酶解开包含蛋造基因的两条 DNA 链。

10.Polymerase chain reaction, or PCR for short, is a technique used in molecular biology to amplify a segment of DNA.

聚合酶链式反应，简称PCR，是一种于放大扩增特定DNA片段的分子物学技术。

11.Then, DNA polymerase and ligase again fill in and repair the cut strand.

然后， DNA 聚合酶和连接酶再次填充并修复被切断的链。机翻

12.Reverse transcription turns viral RNA into DNA that polymerase enzymes can then properly amplify.

逆转录将病毒 RNA 转化为 DNA， 然后聚合酶可以适当地扩增该 DNA。机翻

13.Pluck out his DNA and it could be copied millions of times using a technique called the polymerase chain reaction (pcr).

取出他的遗传物，利聚合酶链反应技术可以复数百万次。

14.When copying the mutated gene, DNA polymerase can basically lose track of which CAG it's on and accidentally add extra CAGs.

在复突变基因时，DNA聚合酶基本上无法定位它所处的CAG位置，并由此意外添加了额外的CAG。

15.The DNA polymerase, which is what makes new DNA, comes in and sees these bases and can synthesize the pairs to them.

DNA 聚合酶，就是造新 DNA 的酶，进来看到这些碱基并能合成成对的碱基。

16.Finally, DNA polymerase fills the gaps on both sides of the union and DNA ligase seals the bond.

最后，DNA聚合酶会填补两侧连接处的空；DNA连接酶会将化学键连接起来。

17.When it comes to medical tests that diagnose COVID, there are two main options, the antigen or rapid test and the polymerase test.

现存主要有两种检测新冠病毒的医学测试方法，一种是抗原或快速检测，另一种是聚合酶链式检测即核酸检测。

18.Then a DNA polymerase synthesizes nucleotides to extend End 1 until it reaches a sequence that's complementary to End 2.

接着，DNA聚合酶会合成核苷酸延长End 1，直到该序列能与End 2互补为止。

19.The third step is called extension - we want to make the environment as optimal as possible for Taq polymerase to do its job.

第三步叫作延伸，我们希望尽可能使环境最优，让Taq聚合酶完成它的工作。

20.To confirm the diagnosis, a reverse transcription polymerase chain reaction or RT-PCR test can be done, which can detect very small amounts of viral RNA.

确诊COVID-19感染需要进行逆转录-聚合酶链式反应（RT-PCR）测试，它能够检出非常微量的病毒RNA。
