Once a peptide has been formed between the amino acid attached to the tRNA in the P site and the amino acid associated with the tRNA in the A site,which process on the list occurs next?
A)translocation
B)reading of the next codon of mRNA
C)initiation
D)the codon-anticodon hydrogen bonds holding the tRNA in the A site are broken

Question

Quizplus · Accepted Answer

Once the peptide bond has been formed, the ribosome undergoes a translocation process, in which the tRNA in the P site moves to the E site and is released, while the tRNA in the A site moves to the P site, bringing the growing polypeptide chain with it. This movement exposes the next codon of mRNA for decoding by a new tRNA molecule. Therefore, choice A is the next process that occurs.
