Which of the Following Is NOT a Basic Step in Protein

Which of the following is NOT a basic step in protein synthesis?

A) The elongation reaction transfers the peptide chain from the peptidyl-tRNA in the A site to the aminoacyl-tRNA in the P site.
B) The P site is occupied by peptidyl-tRNA carrying the growing polypeptide chain.
C) Binding of mRNA by the small subunit is followed by association of a particular initiator aminoacyl-tRNA that recognizes the first codon.
D) The new,longer peptidyl-tRNA moves from the A site into the P site as the ribosome moves one codon further along the mRNA.
