G2 is a phase that indicates the gap between when DNA synthesis occurs and when the next mitotic event occurs.
2期是在DNA合成期完成后,到分裂期开始前的间期
-
It does that through a process of DNA synthesis.
这个过程是通过DNA合成来完成的
-
So either a potassium cyanide or sodium cyanide, these are used in synthesis in terms of making carbon-carbon bonds.
因此无论是氰化钾还是氰化钠，都被用来在合成过程中,制造碳碳键。
-
The reason this fulfillment is important and can be valued is, - according to Richards, that these needs-- unless they are organized or harmonized so that they work together in what he sometimes calls a "synthesis"-- can actually tear us apart.
这种满足之所以重要而有价值是因为，根据Richards的观点，我们的需求-,如果没有被和谐地组织起来,形成一个综合体-,它们会将我们粉碎。

Let's talk about DNA synthesis for a minute.
下面简要介绍一下DNA的合成
-
In order to have DNA you have to make DNA and your cells are continually making DNA inside your body, through a process of DNA synthesis and that synthesis is occurring because of the presence of an enzyme, a protein called DNA polymerase.
为了使每个细胞都具有DNA,身体通过一个叫做DNA合成的过程,不停的生产DNA,这个合成过程是在,一种酶的催化下进行的,这种酶叫做DNA聚合酶
-
But in terms of drugs that don't look like maybe this compound was used in the synthesis, many of them might have used thionyl chloride, because it generates such a nice reactive intermediate that you can go on and make a bunch of different compounds from that intermediate.
但是对于药物来说,它们可能跟合成过程中用到的这种化合物并不相像，很多药物的制造过程中都会用到亚硫酰氯，因为它能产生活性如此之高的反应中间体,以至于你可以继续利用反应中间体,来制造一堆不同类型的化合物。
-
What's shown here is what's called a replication fork in DNA that's undergoing synthesis.
这里展示的是在DNA合成过程中,形成的DNA复制叉
-
Synthesis always occurs in one direction and that makes sense to you now because you know there's a directionality and the chemistry is different going one way than the other and this DNA polymerase only works on the chemistry going in one direction.
NA复制过程是单向的,现在你们该明白原因了,因为DNA单链有方向性,DNA在两个方向上化学性质不同,DNA聚合酶,只在一个方向上起作用
