Options

Choose one · Correct answer highlighted

Frameshift mutations can be caused by insertions or deletions. Silent mutations change the amino acid sequence of a protein. Correct Missense mutations result in a single amino acid change. Nonsense mutations introduce a premature stop codon.

Explanation

Silent mutations do not change the amino acid sequence, as the altered codon still codes for the same amino acid.
