Which of the following correctly describes the formation of the peptide bond?
A)bond formation occurs while the tRNA in the P site moves to the E site, transferring the growing peptide chain to the tRNA that is moving from the A site to P site
B)the growing peptide is transferred first to the 30S subunit of the ribosome, then to the aminoacyl tRNA in the A site
C)bond formation occurs while transferring the growing peptide from the tRNA in the E site to the tRNA in the P site
D)bond formation occurs while transferring the growing peptide from the tRNA in the P site to the tRNA in the A site
E)none of the above

During translation, bond formation occurs between the carboxyl group of the amino acid attached to the tRNA in the P site and the amino group of the incoming aminoacyl tRNA in the A site, forming a peptide bond. The growing peptide chain is transferred from the P site tRNA to the aminoacyl tRNA in the A site during this process. Therefore, option D correctly describes the formation of the peptide bond.
