这里is、call都是谓语,所以有一个连接词what,如果再多一个is,则缺连接词了。其实what we call a chain reaction是一个表语从句,作系动词is的表语。句子意思是“这就是我们所说的连锁反应”。
在句子中,有两个谓语,就有一个连接词;有三个谓语,就有两个连接词。这里is、call都是谓语,所以有一个连接词what,如果再多一个is,则缺连接词了。其实what we call a chain reaction是一个表语从句,作系动词is的表语。句子意思是“这就是我们所说的连锁反应”。 00分享举报为您推荐 jcenter国内镜像 fetch ele...

However, this is not the case any longer. Most of the credit for this advancement goes to Kary Mullis, who invented “Polymerase chain reaction” (PCR) in 1983, marking the beginning of the “Biotechnology Revolution”. Today, PCR is a very common laboratory technique even in smaller labs,...
What is the Polymerase Chain Reaction (PCR)? PCR is a molecular technique frequently applied to amplify regions of interest in DNA, resulting in millions or billions of copies. The PCR reaction is made possible through the use of the thermostable DNA polymerase enzyme known as Taq polymerase. ...
Which enzyme is responsible for copying DNA into an RNA transcript? a. helicase b. spliceosome c. DNA polymerase d. RNA polymerase e. ligase What are the steps for a qRT-PCR? It is a quantitative reaction time polymerase chain reaction. ...

In non-buffered aqueous solutions, ATP is unstable and hydrolyzes into ADP and phosphate. This is because the P-O-P bond in ATP is weaker than the formed phosphate bonds, and the reaction releases energy through hydrogen bonding between the products and water, resulting in an exothermic and ...

An adenine base (A) is paired with every thymine (T) on the template and a cytosine (C) with every guanine (G) and vice versa. Occasionally, one of the four chain-terminating ddNTPs will be inserted by chance, stopping elongation of the DNA st...
