WebMar 19, 2024 · Mutations that do not affect the protein are called silent mutations, because the DNA still makes the same protein that would be expected, and a person with a silent mutation would not even realize it. Other times, the change in the DNA sequence does affect the protein. This can happen, for example, if the DNA sequence CTC is changed to CAC. 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. Webchange a codon to one that encodes the same amino acid and causes no change in the protein produced.
