Correspondence between gene density, CpG island density and H3K4me3 levels across human metaphase chromosomes. Metaphase chromosomes from human lymphoblastoid cells immunostained with antibodies to H3K4me3 are aligned with histograms showing the distribution of genes (filled bars) and CpG islands (open bars) across the same chromosome. The example of each immunostained chromosome shown was selected, for clear and representative banding, from the chromosomes aligned in Additional file 3.
