WebEuchromatin and Heterochromatin The DNA in the nucleus exists in two forms that reflect the level of activity of the cell. Heterochromatin appears as small, darkly staining, irregular particles scattered throughout the nucleus or accumulated adjacent to the nuclear envelope. Euchromatin is dispersed and not readily stainable. WebHeterochromatin is a constituent of eukaryotic genomes with functions spanning from gene expression silencing to constraining DNA replication and repair. Inside the nucleus, heterochromatin segregates spatially …
