Good question.
1. 'Base molecule' means "底物分子". a term of organic chemistry.
2. I think reductionist approach means '还原论的方法', its a little tough here and you made a small mistake.
In short, scientists had been taking a bit of a "we'll deal with that later" approach to the problem, synthesizing the individual components separately before trying to figure out how they could link up. Instead, the researchers found that, by having the phosphate present in the reactions from the start, they could build up a three-ringed structure that would then react with the phosphate.
This is your translation:"简言之,科学家已经对问题取得了“即将解决”的进展,并在尝试弄清它们如何连接起来之前已分别合成了独立的部件。与此不同的是,研究人员通过在反应开始时就加入磷酸分子发现这些分子能够组成一个三环结构并接着和磷酸分子发生反应。“
But I think it would be better if you translate it like this: "简言之,科学家们过去采取了一种”这些事情以后再说“的方法,将构成RNA的分子分别进行合成,然后再考虑怎样把它们连接起来。而今天研究者们发现,让磷酸从一开始就参与整个反应可以在反应中获得一个能和磷酸分子反应的三环结构。”
The latter sentence point out the new method those reseachers used and thats why they succeed.
Although this is specific for the cytosine base, exposing it to UV converted some of it to uridine, the other base of this sort.
3. Although this is specific for the cytosine base, exposing it to UV converted some of it to uridine, the other base of this sort.
I think 'it' refers to the RNA molecure you have just synthesized.[S::P:]
That's my personal understanding, point out any mistakes you found. |
