And eventually, the polypeptide chain will form into the protein.

最，链将形蛋白质。

The polypeptide chain is formed, and will eventually fold into the required protein.

链形，最叠所需的蛋白质。

The ribosome then sticks amino acids together to make a polypeptide chain, following the order of amino acids as coded for, by the mRNA.

然后核糖体将氨基酸粘在一起，形链，遵循 mRNA 编码的氨基酸顺序。

These zymogens are normally activated by proteases which cleave off a polypeptide chain, which is kind of like pulling the pin on a grenade.

这些酶原通过蛋白酶被激活，蛋白酶将一条链切去，这有点像拉手榴弹的保险栓。

This means that their RNA is actually mRNA, and the host cell ribosomes use this mRNA to make a long polyprotein chain, which is then broken into smaller pieces by viral proteases.

这意味着它们的RNA其实就是信使RNA；宿主细胞中的核糖体可以用这些信使RNA制造一条长链，随后被病毒蛋白酶分解小片段。
