The genetic profile - or "genome" - of an organism is determined by recording the full sequence of acid base pairs that make up its DNA.

遗传模式，或者说“基因”，记录于酸碱对序列构成的DNA中，确定着一个生物个体。

A single mutation, a different sequence in the DNA, causes the ribosome to use a different amino acid when it builds the lysozyme molecule.

单一突变，dna序列发生变化，会造成核糖体在构建溶解酵素分子时使用不同的氨基酸。
