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

最终，多肽链将形成蛋白质。

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

多肽链形成，最终会折叠成所需的蛋白质。

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

糖体将氨酸粘在一起，形成多肽链，遵循 mRNA 编码的氨酸顺序。

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，蛋白酶会将一条多肽链切去，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；宿主细胞中的糖体可以用这些信使RNA制造一条长多肽链，随被病毒蛋白酶分解成小片段。
