Frameshift codon
WebFrameshift mutations will alter all the amino acids encoded by the gene following the mutation. Usually, insertions and the subsequent frameshift mutation will cause the active translation of the gene to encounter a premature stop codon , resulting in an end to translation and the production of a truncated protein. WebMar 3, 2024 · Insertion of one base pair can cause a frameshift mutation changing the entire codon sequence. Insertion of three base pairs may be less harmful than the insertion of a single base pair. This is because three base pair insertion does not cause a frameshift mutation. Insertion of a large piece of DNA can be detrimental.
