WebJul 15, 2014 · Nonesense mutations can lead to truncated polypeptides, destroying protein function. A missense mutation will change the amino acid sequence. This may alter the function of the protein, usually negatively, but sometimes positively. This later case may be favored by evolution, as the change is heritable. WebMissense mutations cause a single amino acid change in the protein. Nonsense mutations make a premature "stop" codon. Any codons after that are not translated, and the resulting protein is missing amino acids. Silent mutations code for the same amino acid as before. Insertion and Deletion Mutations Insertion mutations add one or more DNA bases.
