frameshift mutation

Pronunciation: /ˈfreɪmʃɪft mjuˌteɪʃ(ə)n/


A mutation caused by the addition or deletion of a base pair or base pairs in the DNA of a gene resulting in the translation of the genetic code in an unnatural reading frame from the position of the mutation to the end of the gene.
Example sentences
