And triplet codons that encode the same amino acid are defined as synonymous codons.

编码相同氨基酸的三联体密码子被定义为同义密码子。

We asked whether life needs multiple synonymous codons to encode a single amino acid.

我们询问生命是否需要多个同义密码子来编码单个氨基酸。

We took the four-million-character DNA of E. coli, its genome, and completely rewrote the code of this microbe in a very specific way by replacing targeted codons in its genome with synonymous codons that encode the same amino acid.

我们提取了大肠杆菌的 400 万个字符的 DNA，即它的基因组，并通过用编码相同氨基酸的同义密码子替换其基因组中的目标密码子，以一种非常特殊的方式完全重写了这种微生物的代码。
