Figure 7.

Example of small RNAs overlapping a bidirectional promoter. The histograms show frequencies of transcription start sites (TSS) captured by CAGE. Top and bottom panels show CAGE tag-defined TSS mapping to forward and reverse strand, respectively. The shaded grey box indicates the region with potential for forming a dsRNA by transcription on both strands. The location of the small RNA cluster inside this region is indicated in the central panel as a white box. The numbering of genomic nucleotides is assigned by defining the center of the small RNA cluster as +1.
