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?
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 lead to an amino acid encoding codon being changed to a stop codon, thus
resulting in the production of a shortened protein.
