WebA missense mutation is an alteration in the DNA sequence that results in a different amino acid being incorporated into the structure of a protein. Depending on which amino acid it codes for, missense mutations can be conservative (i.e., the resulting protein is functional) or nonconservative (i.e., the resulting protein is non-functional). Web4 nov. 2024 · Nonsense: A nonsense variant is another type of substitution.
