Origin of the translation system and the genetic code in the RNA World. Step 7: The proto-large subunit, R L , evolves the capacity to bind aminoacyl-T RNAs, resulting in more precise amino acid positioning on R L . The activity of R L switches from amino acid ligation to transpeptidation, resulting in an increased peptide yield.
