Figure 5From: Evolution of conserved secondary structures and their function in transcriptional regulation networksComparison of distribution of the number of intergenic CSSs associated with transcription factor-encoding and other genes. The fraction of transcription factor-encoding and other protein coding genes that have four or less (<= 4) or more than 4 (>4) CSSs are shown. About 30% of the transcription factor-encoding genes, compared to about 15% of other genes, are associated with > 4 intergenic CSSs.Back to article page
