Conserved snoRNA box motifs. Conservation pattern of snoRNA U29. In the #Boxes line nt marked with C, D, and d belong to the box C, box D, and box D’, respectivley. The consensus secondary structure in dot-bracket notation provides the typical terminal stem with the unpaired nucleotides inbetween. The region upstream of the box D’ is highly conserved. It is the putative antisense element for guiding a modification. The region upstream of the box D is less conserved than box D’
