Section 5. Place of RNA in the origin and early evolution of translation/Pre-translational coding of peptides. The view that is presented in this crucial segment posits a pre-translational mechanism (side-by-side tRNA mediated coding) that very much resembles the ribosomal entropic system, which could be very advanced. What if the pre-translational coding was assembly line-like and mediated by the aminoacyl-tRNA synthetases themselves? See PMID: 23991065 for one such alternative and a related previous model (PMID: 22210458). This would also match commentary of a possible early origin of non-ribosomal peptide synthesis machinery compared to that of the ribosome.
