Put the following protein synthesis steps in order: A -- Attack of the free amino group from the aminoacyl-tRNA in the A-site onto the carbonyl end of the peptide in the P-site. B -- Binding of a peptidyl-tRNA carrying the amino acid methionine. C -- Binding of mRNA by the small subunit. D -- Release factor signals hydrolysis of the peptidyl-tRNA. E -- Association of the large ribosomal subunit. F -- Peptidyl-tRNA moves from the A-site into the P-site, and the ribosome moves one codon further along the mRNA.
