If a gene is highly expressed, that means it’s getting used to make lots of RNA, which usually means more of that gene’s protein is getting made.

如果一个基因被高度表达，这意味着它被用来制造大量的 RNA， 这通常意味着该基因的更多蛋白质正在被制造。

Experimental science progresses by holding steady one variable at a time, an approach that is not always easy when dealing with networks of genes, proteins or other molecules.

实验科学通过每次控制一个变量来获取进展，但在处理基因、蛋白质或其他分子的网络时，这种方法时有困难。
