Euchromatin - Wikipedia

WebDNA is packed into chromosomes in the form of chromatin, also know as supercoiled DNA. And so, chromatin is made up of DNA, histone proteins, and non-histone proteins. And there are repeating units in chromatin, called nucleosomes, which are made up of 146 base pairs of double helical DNA that is wrapped around a core of eight histones. Webeuchromatins converted to a heterochromatin state centromere a constricted region of a chromosome that inclues the site of attachment to the mitotic spindle heterochromatin (and therefore repetitive sequence) not defined by DNA sequences but rather by chromatin structure (histones) length of DNA required for centromeric function is often long farmland opportunity jay girotto

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.
