Can euchromatin become heterochromatin
Chromatin is found in two varieties: euchromatin and heterochromatin. Originally, the two forms were distinguished cytologically by how intensely they get stained – the euchromatin is less intense, while heterochromatin stains intensely, indicating tighter packing. Heterochromatin is usually localized to the periphery of the nucleus. Despite this early dichotomy, recent evidence in both animals … Weblab_slides->euchromatin_and_heterochromatin; $title= $slide_name->title; ?> ... Slide List
