Table 1 The 25 theoretical minimal RNA ring sequences. Columns are: 1) RNA ring numbering; 2) RNA ring cognate amino acid according to homology hypothesis with ancestral tRNAs [12]; 3) RNA ring with stop codon at 3′ extremity, anticodon underlined. Presumably, three consecutive translation rounds translated RNA rings, starting at the 3′ side of the stop codon
