Missense, nonsense, and silent mutations are all caused by single base changes in the coding region of a gene. How

are these three types of mutations different?



What will be an ideal response?


ANSWER: Silent mutations do not lead to an amino acid change in the resulting protein encoded by the
DNA. Missense mutations do lead to an amino acid change in the resulting protein encoded
by the DNA. Nonsense mutations change a codon that specifies an amino acid into a stop
codon, thus resulting in the production of a shortened protein.
