Euchromatin is the genetically active type of chromatin involved in transcribing RNA to produce proteins used in cell function and growth. The predominant type of chromatin found in cells during interphase, euchromatin is more diffuse than the other kind of chromatin, which is termed heterochromatin.
Sex chromatin is readily studied in smears taken from the buccal mucosa with a spatula and spread onto microscope slides. Once the buccal mucosal cells are fixed and stained by a simple nuclear dye (e.g., cresyl violet), the sex chromatin body can be observed in approximately 30% of cells from normal females, and in no cells from normal males.
