in addition , this analysis leads us to propose that ( i ) some of the highly conserved nucleotide residues in single-stranded regions interact in a specific manner with protein components of the translational apparatus , and ( ii ) repetitive folding and unfolding of helical regions occurs in two regions of eukaryotic 5s rrna and one region of eubacterial 5s rrna .
