Comparison of ORC and MCM2 data within the set of ORC-MCM2 sites. A. Length of the ORC and MCM2 HMM-called regions is shown. B. Distance between the positions of probes that define ORC and MCM2 peaks in the ORC-MCM2 class of binding sites. Thus "0" means that the peaks identified are the same 50 bp probe and "721+" means that the peaks are more than 9 probes (spaced ~80 bp) apart.
