Detailed explanation-1: -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-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: -They always cause a change to an organism’s genotype. Regardless of the cause of the change, a DNA sequence is always altered when it mutates.
Detailed explanation-4: -B. Silent mutations are a result of the redundancy (degeneracy) of the genetic code: This is false, as silent mutations are the result of a base substitution that has no discernible effect on the amino acid sequence of a protein.
