The packaging of DNA into chromosomes is a highly regulated and complex process that allows the long, linear DNA molecules to be efficiently stored and replicated in the cell. Chromosomes are structures made up of DNA and proteins that are visible under a microscope during cell division. In eukaryotic cells, chromosomes are found in the nucleus, while in prokaryotic cells, they are located in the nucleoid region of the cytoplasm.

The basic unit of chromosome packaging is the nucleosome, which is composed of DNA wrapped around a core of eight histone proteins.
