The 3 base codes are known as codons. So GGT is a " codon" for Glycine.

这三个碱基编码被称为密码子。所以 GGT 是甘氨酸的“密码子”。

Three base codons on the mRNA code for one amino acid.

一个氨基酸的 mRNA 编码上的三个碱基密码子。

The words in which the instructions are written are called codons, and the letters are known as bases.

指令中所写的单词被称为密码子，单词中的一个个字母被称为碱基。

The genetic code is a rulebook that defines which codon encodes which amino acid.

遗传密码是一本规则手册，它定义了哪个密码子编码哪个氨基酸。

So, for example, the triplet codon TCG encodes the amino acid serine.

因此，例如，三联密码子 TCG 编码氨基酸丝氨酸。

So, for example, the amino acid serine is encoded by six different triplet codons.

因此，例如，氨基酸丝氨酸由六个不同的三联体密码子编码。

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。

And this means that most amino acids are encoded by more than one triplet codon.

这意味着大多数氨基酸由不止一个三联体密码子编码。

And the order of triplet codons in DNA encodes the order of amino acid building blocks in a protein.

DNA 中三联体密码子的顺序编码了蛋白质中氨基酸组成部分的顺序。

For example, does life need six different codons, which all code for the amino acid serine?

例如，生命是否需要六个不同的密码子，它们都编码氨基酸丝氨酸？
