Question

Which one of the following statements about mutation types is correct?

a. Silent mutations are changes in DNA sequence that alter the amino acid, and they do not change the biological function of the altered sequence.

b. Neutral mutations are changes in DNA sequence that are reversed by a second mutation, resulting in the same amino acid as the original, unmutated amino acid.

c. Neutral mutations are changes in DNA sequence that produce synonymous codons specifying the same amino acid.

d. Missense mutations alter the coding sequence. One amino acid is substituted for another.

e. Missense mutations change a codon originally specifying an amino acid into a translation-termination codon.

Explanation / Answer

e. Missense mutations change a codon originally specifying an amino acid into a translation-termination codon.
