The internal motif (IM) of the me-ncRNAs. A: Logo of the IM (WebLogo [52]). B: The relationship between IM frequency and PriMir Score. The ml-ncRNAs were binned according to their PriMir score, and the fraction of transcripts with the IM were plotted. Blue circles: All ml-ncRNAs. Red triangles: ml-ncRNAs with conserved stem-loops. C: Frequency of IM in experimentally supported me-ncRNAs, unsupported ME-ncRNA candidates, other ml-ncRNAs, and in flanking sequence of intronic miRNAs.
