SHARED MOTIFS. “Each RNA nucleotide of any natural RNA sequence is part of one of these secondary structure motifs: stem, loop, bulge, junction or end, or another unpaired region. This means that the composition of RNA bases follows the stem-loop architecture as an appropriate tool, to store information and build more complex ensembles that together act catalytically as ribozymes.”
