All of the following are Stop Codons EXCEPT

Correct answer: D. AUG

  • A. UGA
  • B. UAG
  • C. UAA
  • D. AUG

Explanation

AUG is not a stop codon; it is the start codon (specifically, the initiation codon) that signals the beginning of protein synthesis during translation. UGA, UAG, and UAA are the three stop codons, also known as termination codons, that signal the end of the protein-coding sequence.
