WebEuchromatin is defined as a region of the chromosome that is densely packed with genes and actively participates in the transcription process. It can be found in the … 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, … 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 • Heterochromatin formation involves changes in histone modifications over multiple cell generations – Katan-Khaykovich Y, Struhl K (June 2005). "Heterochromatin formation involves changes in histone modifications over multiple cell generations" See more Transcription Euchromatin participates in the active transcription of DNA to mRNA products. The unfolded structure allows gene regulatory proteins and RNA polymerase complexes to bind to the DNA sequence, which can then initiate the … See more • Histone Modifying Enzymes • Constitutive Heterochromatin See more
