The mechanisms by which such … Replication Labeling Reveals Solid-like Behavior of Euchromatin and Heterochromatin in Living Cells, and Heterochromatin-Associated Proteins Exhibit Liquid-like Behavior To ascertain whether condensed chromatin in the nucleus is a liquid, the extent of mixing in heterochromatin and euchromatin regions of mouse C3H/10T1/2 cells was determined. Euchromatin and heterochromatin are the two structural forms of DNA in the genome, which are found in the nucleus. Both euchromatin and heterochromatin contain nucleosomal particles (composed of two molecules each of histones H2A, H2B, H3 and H4), however histones have been shown to regulate genes in these regions in quite different ways.
