What is Chromatin

WebWe can define three levels of chromatin organization in general terms: DNA wrapped around histone proteins (n ucleosomes) like “beads on a string”. Multiple nucleosomes coiled (condensed) into 30 nm fiber (solenoid) structures. Higher-order packing of the 30 nm fiber into the eventual familiar metaphase chromosome. WebIn eukaryotes, genomic DNA is packaged into chromatin in the nucleus. The accessibility of DNA is dependent on the chromatin structure and dynamics, which essentially control DNA-related processes, including transcription, DNA replication, and repair. All of the factors that affect the structure and dynamics of nucleosomes, the nucleosome–nucleosome …
