In a mutation,
A)the new codon may specify a different amino acid but may not change the function of the new protein produced.
B)the new codon may specify the same amino acid as the old codon.
C)the new codon and resulting amino acid may destroy the function of the protein specified.
D)the new codon may specify no amino acid.
E)all of these may be true.

All of the choices may be true in a mutation. Point mutations can result in a change in the amino acid specified by the codon, but this may or may not affect the function of the resulting protein. Sometimes a different amino acid can still work as intended, while other times it can alter the protein's structure or function. In some cases, the new codon may specify the same amino acid as the old codon, leading to no change in the resulting protein. However, in other cases, the change in nucleotide sequence can result in a premature stop codon or other non-coding sequence, leading to a non-functional protein.
