The code is read, three bases at a time, by a series of transfer RNA (tRNA) molecules, which recognize the mRNA message and align the appropriate amino acid in place.

一系列转移RNA分子将每三个碱基读成一个密码子，识别出mRNA的信息并将氨基酸相应排列起来。

For example, this transfer RNA has a unit here, at one end of the transfer RNA molecule.

举个例子,这个tRNA的一端,有一个GAG的碱基序列单元
