So if we have cells that make new proteins with new functions, could we get them to do things that natural cells can't do?

因此， 如果我们的细胞可以制造具有新功能的新蛋白质，我们能否让它们做自然细胞不能做的事情？

The translational machinery of natural cells -- including ribosomes, aminoacyl-tRNA synthetase enzymes and tRNAs -- is a unique and special system for making proteins in which the 20 common amino acids are strung together in a chain.

天然细胞的翻译机制——包括核糖体、氨酰-tRNA 合成酶和 tRNA——是一种独特而特殊的系统，用于制造蛋白质，其中 20 种常见氨基酸串成一条链。
