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. 92% of the human genome is euchromatic. [1]

真染色質（英文： Euchromatin ，又譯同染色質或常染色质）是基因密度較低的染色質，多在细胞周期的S期进行复制，且通常具有轉錄活性，能夠生產蛋白質。
Euchromatin - Definition, Function, Structure & Quiz - Biology …
2019年4月8日 · Euchromatin is a form of chromatin that is lightly packed—as opposed to heterochromatin, which is densely packed. The presence of euchromatin usually reflects that cells are transcriptionally active, i.e. they are actively transcribing DNA to mRNA. Euchromatin is found in the nucleus of eukaryotes and represents more than 90% of the human genome.

Euchromatin- Definition, Structure, Functions, Regulation
2023年8月3日 · Euchromatin comprises repetitive units of DNA helix wrapped around histone proteins in a more open state to allow easy transcription. Euchromatin is specifically marked by histone modifications via methylation and acetylation to facilitate gene expression.
Molecular Complexes at Euchromatin, Heterochromatin and …
Euchromatin is characterized by active genes, wider spacing between nucleosomes, higher accessibility to transcription machinery, histone modifications and variants that facilitate active transcription [30,31,32,33,34,35,36]. The more open, unfolded structure of euchromatin allows transcriptional machinery to bind to the DNA, thereby ...
Euchromatin - an overview | ScienceDirect Topics
Euchromatin is lightly packed nucleosomes, commonly referred to as “beads on a string,” that allows transcription to occur on exposed genes. Heterochromatin is tightly packed nucleosomes forming a 30-nm fiber that does not allow transcription of enclosed genes to occur.
Heterochromatin and Euchromatin - SpringerLink
Heterochromatin and euchromatin are two major categories of chromatin higher order structure. Heterochromatin has condensed chromatin structure and is inactive for transcription, while euchromatin has loose chromatin structure and active for transcription.
Is euchromatin really open in the cell? - Cell Press
2023年6月27日 · New evidence from genomics and advanced imaging studies has revealed that euchromatin consists of condensed liquid-like domains. Condensed chromatin seems to be the default chromatin state in higher eukaryotic cells. We discuss this novel view of euchromatin in the cell and how the revealed organization is relevant to genome functions.
Finishing the euchromatic sequence of the human genome
2004年10月21日 · Although the euchromatic genome sequence has reached a much higher degree of completion than had been anticipated, it still remains incomplete with ∼ 1% of the euchromatin residing in 308 gaps ...
