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. 92% of the … See more Euchromatin is composed of repeating subunits known as nucleosomes, reminiscent of an unfolded set of beads on a string, that are approximately 11 nm in diameter. At the core of these nucleosomes are a … See more Euchromatin resembles a set of beads on a string at large magnifications. From farther away, it can resemble a ball of tangled thread, such as in some electron microscope visualizations. In both optical and electron microscopic visualizations, euchromatin … See more Euchromatin is primarily regulated by post-translational modifications to its nucleosomes’ histones, conducted by many histone-modifying enzymes. These modifications occur … See more Transcription Euchromatin participates in the active transcription of DNA to mRNA products.
