The Appropriate Order for the Basic Steps of Protein Synthesis

question 22

Multiple Choice

The appropriate order for the basic steps of protein synthesis are:
A.The elongation reaction transfers the peptide chain from the peptidyl-tRNA in the P site to the aminoacyl-tRNA in the A sitE.
B.The P site is occupied by peptidyl-tRNA carrying the growing polypeptide chain.
C.Binding of mRNA by the small subunit followed by association of a particular initiator aminoacyl-tRNA that recognizes the first codon.
D.The large ribosomal subunit joins the initiation complex, preparing it for the elongation stagE.E.The new, longer peptidyl-tRNA moves from the A site into the P site as the ribosome moves one codon further along the mRNA.
