Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division, preventing DNA damage, and regulating gene expression and DNA replication. During mitosis and WebApr 8, 2024 · Structure and Formation of Chromatin and Chromosomes The main element of chromatin structure is the nucleosome which is a complex of DNA and histones.

WebThe dynamic organization of chromatin structure thereby influences, potentially, all functions of the genome. The fundamental unit of chromatin, termed the nucleosome, is composed of DNA and histone proteins. This structure provides the first level of compaction of DNA into the nucleus. WebThe chromatin condenses and the cell gets ready to get separated into two cells. I don't know it exactly, but I guess it is coming from "before" the microtubules attach. "Meta" means after or adjacent in ancient Greek. So, after the microtubules attach and now start to pull the chromosomes apart. "Ana" means up or back in ancient Greek.
