Noun
euchromatin (countable and uncountable, plural euchromatins)
(genetics) uncoiled dispersed threads of chromosomal material that occurs during interphase; it stains lightly with basic dyes
Although most of its genome can be characterized as euchromatin, S. cerevisiae has regions of DNA that are transcribed very poorly. Source: Internet
An example of facultative heterochromatin is X chromosome inactivation in female mammals: one X chromosome is packaged as facultative heterochromatin and silenced, while the other X chromosome is packaged as euchromatin and expressed. Source: Internet
Not all euchromatin is necessarily transcribed, but in general that which is not is transformed into heterochromatin to protect the genes while they are not in use. Source: Internet
The basic structure of euchromatin is an elongated, open, 10 nm microfibril, as noted by electron microscopy. Source: Internet
This lighter staining is due to the less compact structure of euchromatin. Source: Internet
