Fig. 4. Comparison and distribution of minimal genomic locus-PML body distances. The distribution of minimum distances between each genomic locus and its nearest PML body is shown as a box and whiskers plot, where the box extends from the lower quartile (where 25% of observed genomic locus-PML body distances are smaller), to the upper quartile (where 25% of observed genomic locus-PML body distances are larger) and the horizontal line in the middle of the box is the median. The small circles show outlying points and the ‘whiskers’ extending from the box show the range of minimum genomic locus-PML body distances. Note that the distribution of minimal MHC-PML distances is clearly shorter in comparison to the minimal EDC-PML and 6p24-PML distances.
