Histograms depicting the distance from Tf insertion sites to the nearest ORF. The numbers of Tf insertions closer to the 5′ ends of adjacent ORFs and to the 3′ ends of adjacent ORFs were determined. The corresponding histograms were constructed by including insertions closer to the 5′ end of an ORF on the upstream side of the ORF (cross-hatched). Insertions closer to the 3′ side of an ORF were included on the downstream side of the ORF. The insertions are binned in regions of 100 bp.
