I see the polymerase and the enzymes and so forth.

我看到还有生化等等。

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

现存主要有两检测新冠毒的医学测试方法，一抗原或快速检测，另一链式检测即核酸检测。

Ok, see, Taq polymerase is actually a really cool enzyme.

看，Taq其实一很酷的。

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在复制时比DNA更容易产生错误，因此在转录过程中经常出错，也就为什么RNA毒的突变比DNA毒发生得更频繁。

Every day, beginning from today, courier personnel who are primarily from local meal delivery and e-commerce platforms are subjected to a polymerase chain reaction (PCR) test and antigen self-testing.

从今天开始，每天对主要来自当地送餐和电子商务平台的快递人员进行链反应（PCR）测试和抗原自我检测。

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-链式反应（RT-PCR）测试，它能够检出非常微量的毒RNA。

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

DNA ，就制造新 DNA 的，进来看到这些碱基并能成成对的碱基。

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

取出他的遗传物质，利用链反应技术可以复制数百万次。

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 解开包含蛋白质制造基因的两条 DNA 链。

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

链式反应，或PCR，可能被用来筛查出特定因，比如HIV、肠道毒、HSV、肺结核毒等。

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

接着科学家们应用链式反应，简称 PCR，使用一被称为通用引物的人工成 DNA 链。

Their main method of destruction is blocking the action of enzymes called RNA polymerase.

它们的主要破坏方法阻断 RNA 的作用。

The gold standard for diagnosis of COVID-19 is RT-PCR, or reverse transcription polymerase chain reaction.

诊断COVID-19的金标准RT-PCR，即逆转录-链式反应。

Inside the nucleus, the DNA molecule is unzipped from around the gene by DNA polymerase.

在细胞核内，DNA 分子被 DNA 从基因周围拉开。

With RNA viruses, many of them stay in the cytoplasm where the viral RNA is used by the host's ribosomes to create viral RNA polymerase proteins.

对于RNA毒，它们中的许多都待在细胞质中，毒RNA在这里由宿主的核糖体成毒RNA。

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

在复制突变基因时，DNA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。

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

链式反应，简称PCR，一用于放大扩增特定DNA片段的分子生物学技术。

RNA polymerase also then binds the RNA nucleotides together making a new RNA strand.

然后 RNA 也将 RNA 核苷酸结在一起，形成新的 RNA 链。

So not only can Taq polymerase withstand the heat during the denaturation step of PCR, but it also functions best at around 72 degrees Celsius.

因此，Taq不仅能承受PCR变性步骤中的热量，而且在72摄氏度左右能发挥出最好的作用。

Now this virus is a single-stranded RNA virus, and it's also a negative sense, meaning it first has to be transcribed by RNA polymerase into a positive-sense mRNA strand.

麻疹毒一单链RNA毒，也就负义链的毒，这意味着它首先必须被RNA转录成正义mRNA链（正义链与反义链互补）。
