The chromatin complex is a dynamic structure within the cell nucleus composed of DNA, histone proteins, and various non-histone proteins. Chromatin undergoes structural changes to regulate gene expression, DNA replication, repair, and recombination.The basic unit of chromatin is the nucleosome, which consists of DNA wrapped around a core of histone proteins. Nucleosomes are connected by linker DNA and higher-order structures form through the folding and packing of nucleosomes.Chromatin can exist in different states, including euchromatin, which is loosely packed and associated with active gene expression, and heterochromatin, which is densely packed and generally associated with gene silencing. The transition between these states is tightly regulated and involves modifications to histone proteins, DNA methylation, and the recruitment of various chromatin-modifying enzymes and regulatory proteins.
