What is the initiator triplet in both prokaryotes and eukaryotes? Which amino acid does this triplet recruit?
A)UAA; no amino acid called in
B)UAA or UGA; arginine
C)AUG; arginine
D)AUG; methionine
E)UAA; methionine

Question

Quizplus · Accepted Answer

The initiator triplet in both prokaryotes and eukaryotes is AUG, and it recruits methionine as the first amino acid in the polypeptide chain. Option A is incorrect because UAA is actually a stop codon and does not recruit any amino acid. Option B is incorrect because UGA is also a stop codon and does not recruit arginine. Option C is incorrect because UAA is a stop codon and does not recruit arginine, and AUG recruits methionine and not arginine. Option E is incorrect because UAA is a stop codon and does not recruit methionine.
