Circular RNA without a stop codon enables rolling circle translation. To produce circular RNAs, we carried out one-pot chemical synthesis of circular RNA from RNA fragments with the use of an EDC/HOBt-based chemical ligation reaction. The synthesized circular RNAs acted as translation templates, despite the presence of unnatural phosphoramidate linkages.
