What is the initiator triplet in both bacteria and eukaryotes? What amino acid is recruited by this triplet?

B)AUG; methionine
C)AUG; arginine
D)UAA,UGA,or UAG; arginine
E)UAA,UGA,or UAG; methionine

Question

Quizplus · Accepted Answer

The initiator triplet in both bacteria and eukaryotes is AUG, and it recruits the amino acid methionine. Option A is incorrect because UAA, UGA, and UAG are stop codons and do not recruit any amino acid. Options C and D are incorrect because AUG recruits methionine, not arginine. Option E is incorrect because UAA, UGA, and UAG are stop codons and do not recruit any amino acid, and even if they were initiator triplets, they still would not recruit methionine.
