Chromatin remodeling is a fundamental biological process that alters the structure of chromatin, the complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. This remodeling is essential for a wide range of cellular functions, including DNA replication, repair, and gene expression. Essentially, chromatin remodeling involves repositioning nucleosomes, the basic repeating units of chromatin, which are composed of DNA wrapped around histone proteins.
There are several mechanisms by which chromatin can be remodeled. One primary mechanism involves ATP-dependent chromatin
The dynamic nature of chromatin remodeling ensures that specific regions of the genome are accessible or inaccessible
