During translation,what is the correct order of events that occur as an amino acid is added?
A) codon recognition, peptide bond formation, translocation
B) translocation, codon recognition, termination
C) initiation, codon recognition, termination
D) peptide bond formation, translocation, codon recognition

Question

Quizplus · Accepted Answer

The correct order of events during translation is codon recognition (matching the mRNA codon to the appropriate anticodon on the tRNA), peptide bond formation (the amino acid on the tRNA in the A site is joined to the growing polypeptide chain by a peptide bond), and translocation (the ribosome shifts down the mRNA by one codon, moving the tRNA in the A site to the P site and the tRNA in the P site to the E site). Therefore, option A is the correct choice. Option B is incorrect because termination occurs after the last amino acid has been added, and translocation occurs before termination. Option C is incorrect because initiation occurs before codon recognition, and termination occurs after the last amino acid has been added. Option D is incorrect because peptide bond formation occurs before translocation.
