Euchromatin - Wikipedia
Euchromatin (also called "open chromatin") is a lightly packed form of chromatin (DNA, RNA, and protein) that is enriched in genes, and is often (but not always) under active transcription . Euchromatin stands in contrast to heterochromatin, which is tightly packed and less accessible for transcription. en.wikipedia.org

Heterochromatin
Structure Chromatin is found in two varieties: euchromatin and heterochromatin. Although most of its genome can be characterized as euchromatin, S. cerevisiae has regions of DNA that are transcribed very poorly. wikipedia.org
