Comparison of inter-nucleosomal distances between five species in their nucleosome arrangement within the genic region. The canonical inter-nucleosomal distance (bp) between two neighboring nucleosomes (for example, +1 and +2) was calculated as the peak-to-peak distance, which was measured in the composite distribution of in vivo nucleosome locations. The nucleosome distribution of each species was produced as described in Methods. The nucleosomal repeat length (as an averaged distance between neighboring nucleosomes) is reported in Supplemental Table S2B.
