  [遗] 无义突变

...指DNA分子中碱基对的取代,使得mRNA的某一密码子发生变化,由他所编码的氨基酸就变成另一种不同的氨基酸,使得多肽链中氨基酸的顺序也相应地发生改变。无义突变(nonsense mutation)指由于碱基取代使原来可翻译某种氨基酸的密码子变成了终止密码子。

Nonsense mutation

  • In genetics, a nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and usually nonfunctional protein product. It differs from a missense mutation, which is a point mutation where a single nucleotide is changed to cause substitution of a different amino acid.
