Answer and explanation

Correct answer: C. Nonsense mutation

  1. Step 1: Missense mutations alter one amino acid to another. Step 2. Silent mutations change the codon without altering the coded amino acid. Step 3. Nonsense mutations introduce a premature stop codon, terminating translation early. Answer: Nonsense mutation. Why not the others: Premature stop codons define nonsense mutations.
