Sites of open chromatin are preferentially associated with DSB hotspots

[i] Shown are the percentages of base pairs from each sample (top) that overlap with DSB hotspots (Blitzblau et al. 2007; Buhler et al. 2007). Permuted values are the average derived from 10 permutations of FAIRE site positions (Methods).
[ii] aObserved/expected ratios indicate the strength of association between the sample and DSB hotspots.
[iii] bP < 0.0001.
