Multiple Choice
Which of the following events is NOT part of prokaryotic translation initiation?
A) IF-3 separates ribosome subunits so that a small subunit can bind mRNA through base pairing of the 16S rRNA and the Shine-Dalgarno sequence on the mRNA.
B) An initiator tRNAformylmet binds the initiation codon, with the help of IF-1 and IF-2 complexed with GTP. The tRNAformylmet is positioned in the P site.
C) A peptide bond is formed by the peptidyl transferase activity of the large subunit rRNA. The polypeptide chain on the tRNA in the P site is transferred to the amino acid on the tRNA in the A site.
D) IF-3 dissociates, allowing a large subunit to bind the 30S initiation complex.
