The reason why it is impractical to proofread the step that hydrolyzed peptide bond formed previously after the insertion of incorrect amino acid. Introduction : The proofreading mechanisms used during replication and protein synthesis are different. DNA (deoxyribonucleic acid) polymerase use 3 ′ → 5 ′ exonuclease activity to remove mispaired nucleotides. However, there is no such analogous proofreading function on ribosomes. Proofreading translation after the incorporation of amino acid into growing peptide would be impractical.
