Detailed explanation-1: -Definition. A missense mutation is a DNA change that results in different amino acids being encoded at a particular position in the resulting protein. Some missense mutations alter the function of the resulting protein.
Detailed explanation-2: -A mutation in the amino acid sequence may alter the structure of a protein but it does not necessarily alter its function, although, the mutation at specific sites such as conserved residues can bring about a change in the structure and function of the protein.
Detailed explanation-3: -Mutations in a gene can result in a change in the sequence of amino acids such as in frameshift mutations and in missense and nonsense mutations occurring in point mutations. However, point mutations can also lead to silent mutations.
Detailed explanation-4: -change a codon to one that encodes the same amino acid and causes no change in the protein produced. These are called silent mutations.
