Unformatted text preview: specifying that amino acid? A. binding the correct incoming aminoacyl-tRNA to the A site on the ribosome (codon-anticodon pairing). B. the formation of a peptide bond between the peptide in the P site on the ribosome with the amino acid on the correctly paired aminoacyl-tRNA in the A site. C. the charging of the tRNA with the correct amino acid by the aminoacyl-tRNA synthetase. D. formation of a 30S initiation complex. E. none of the above 4.
