RNAPII is preferentially positioned on pre-miRNA genomic sequence. Position zero on X axis corresponds to the center of pre-miRNA genomic sequence. (A) The occupancy profiles of RNAPII across a 2,000-nt window surrounding the centers of pre-miRNA genomic sequences corresponding to active-promoter miRNA, inactive-promoter miRNA, expressed miRNA and unexpressed miRNA in CD4+ T cell. (B) The occupancy profiles of RNAPII across a 2,000-nt window surrounding the center of pre-miRNA genomic sequence in Jurkat T cell.
