Abstract: Small circular RNAs occur in many cells. Theoretical considerations designed to mimick primordial RNAs designed 25 theoretical, minimal 22-nucleotide long circular RNAs (RNA rings) forming stem-loop hairpins, including one codon per amino acid, a start… read more here.

Abstract: Accretions of tRNAs presumably formed the large complex ribosomal RNA structures. Similarities of tRNA secondary structures with rRNA secondary structures increase with the integration order of their cognate amino acid in the genetic code, indicating… read more here.
