Definition of nonsense mutation in English:

nonsense mutation

noun

Genetics

A mutation in which a sense codon that corresponds to one of the twenty amino acids specified by the genetic code is changed to a chain-terminating codon.
〔遗传〕无义突变
Example sentencesExamples
- The first spans codons 195-196 and induces a silent substitution at codon 195 and a nonsense mutation at codon 196.
- The proximity of the nonsense mutation to the start codon indicates that these mutations are null alleles.
- Another nonsense mutation at codon 187 is shared by the human, the chimpanzee and the gorilla, so that it is most likely to have occurred in their ancestral species.
- A nonsense mutation is represented by a solid red circle.
- Another mutant isolated from the screen, LPY727, contained a nonsense mutation at amino acid 15.
