Origin of the 16S Ribosomal Molecule from Ancestor tRNAs
Sávio Torres de Farías, Thaís G. do Rêgo, Marco V. José
Abstract
We tested the hypothesis that concatemers of ancestral tRNAs gave rise to the 16S ribosomal RNA. We built an ancestral sequence of proto-tRNAs that showed a significant identity of 51.69% and a percentage of structural identity of 0.941 with the 16S ribosomal molecule. We also propose a hypothesis for the emergence of translation.
