Correct answer: A. Nonsense mutation

  • A. Nonsense mutation
  • B. Transversion

  • D. Frame shift mutation

Explanation

A nonsense mutation changes a codon specifying an amino acid into a termination codon, causing premature stopping of translation. A silent mutation leaves the amino acid unchanged, whereas a frameshift results from insertion or deletion of nucleotides.
