A mutation that converts an amino acid codon to a stop codon is a_____________?
Correct answer: D. Nonsense mutation
- A. Frame shift mutation
- B. Transversion
- C. Silent mutation
- D. Nonsense 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.
