Distinguishing regulatory domains. Screenshot from the Ancora genome browser showing 26 Mb of human chromosome 10 and HCNE densities from comparisons with mouse, zebrafish and medaka. HCNE density curves are separated based on chromosomes in these organisms (Zv7_NA53 is a contig that has not been assigned to a chromosome). To illustrate the use of this view for distinguishing chromosomal regulatory domains, rectangles have been manually added to the screenshot around density peaks indicating clusters of HCNEs in conserved synteny. Rectangles are labeled with regulatory genes annotated in the corresponding genomic regions.
