Detailed explanation-1: -A genetic mutation is a change to a gene’s DNA sequence to produce something different. It creates a permanent change to that gene’s DNA sequence.

Detailed explanation-2: -While mutations always change the DNA sequence, they do not always cause a change in the resulting protein or an obvious effect on the organism. This can occur because most amino acids can be coded by two or more different codons.

Detailed explanation-3: -Changes to a gene’s DNA sequence, called mutations, can change the amino acid sequence of the protein it codes for-but they don’t always.

Detailed explanation-4: -Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene’s protein.
