Chromatin is found in two varieties
1. Euchromatin
2. Heterochromatin.
Originally, the two forms were distinguished cytologically by how intensely they stained.
euchromatin is less intense, while heterochromatin stains intensely, indicating tighter packing.
Heterochromatin is usually localized to the periphery of the nucleus. Heterochromatin is a tightly
packed form of DNA, which comes in multiple varieties. These varieties lie on a continuum
between the two extremes of constitutive and facultative heterochromatin. Both play a role in the
expression of genes.
