Which of the following statements about translation is incorrect?

During the initiation the ribosome binds mRNA at the AUG start codon and recruits an initiator tRNA carrying methionine.

During elongation the ribosome moves along mRNA in a 5' to 3' direction, and the next tRNA with complementary anticodon enters the A site.

During peptide bond formation the ribosome catalyzes peptide bonds between amino acids at the A site and the growing polypeptide.

During translocation the ribosome moves along mRNA in a 3' to 5' direction, shifting the tRNA at the P site to the A site, and the tRNA at the P site exits.
