Weba. Missense mutation:In missense mutation, there is an alteration in the base pair of DNA. For example, A is replaced by C, as a result, DNA encodes for a different amino acid. Due to the mistake of DNA, a wrong amino acid is incorporated into a protein. The change in the substitution of amino acid may not affect or make the protein non-functional.
