Figure 1From: Different distribution of histone modifications in genes with unidirectional and bidirectional transcription and a role of CTCF and cohesin in directing transcriptionGene promoter types. Genes were subdivided into (A) unidirectional, (B) bidirectional and (C) unidirectional genes with an upstream alternative TSS. The arrows represent TSSs and the figures are centered at the gene TSS.Back to article page
