conceptschromatin
Chromatin is a complex of DNA, histone proteins, and other associated proteins that forms chromosomes within the nucleus of eukaryotic cells. It is the fundamental unit of DNA packaging and organization within the cell. Chromatin exists in two primary states: euchromatin and heterochromatin. Euchromatin is loosely packed and transcriptionally active, while heterochromatin is tightly packed and transcriptionally inactive. The structure and function of chromatin are dynamic and can change in response to various cellular processes, such as gene expression, DNA replication, and cell division.
The basic unit of chromatin is the nucleosome, which consists of a segment of DNA wrapped around
Chromatin structure and function are regulated by various post-translational modifications of histones, such as acetylation, methylation,
Chromatin plays a crucial role in various cellular processes, including DNA replication, transcription, DNA repair, and
