WebFeb 15, 2024 · Chromatin is located in the nucleus of our cells . The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus. Chromatin … 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.

WebEuchromatin consists of approximately 90% of the entire human genome. It covers the maximum part of the dynamic genome to the inner of the nucleus. The structure of euchromatin is similar to the nucleosomes, which includes the histones proteins having about 147 base pairs of DNA wrapped around them. WebEuchromatin is the transcriptionally active form of chromatin. On the other hand, heterochromatin exists in condensed form and is usually present toward the end or pericentric region of the chromosome. Inside the nucleus, heterochromatin could be seen near the periphery and are often clumped. WebFeb 22, 2024 · The large-scale organization of the genome inside the cell nucleus is critical for the cell’s function. Chromatin – the functional form of DNA in cells – serves as a substrate for active nuclear processes such as transcription, replication and DNA repair.
