Nonsense codons bring about__________________?
Correct answer: D. Termination of protein synthesisOrder DNA Kits
- A. Elongation of polypeptide chain
- B. Pre-translational modification of protein
- C. Initiation of protein synthesis
- D. Termination of protein synthesisOrder DNA Kits
Explanation
Nonsense codons, including UAA, UAG and UGA, do not specify amino acids; they signal release of the completed polypeptide. Therefore, they cause termination rather than initiation or elongation.
