WebIn human cells, most DNA is found in a compartment within the cell called a nucleus. It is known as nuclear DNA. In addition to nuclear DNA, a small amount of DNA in humans and other complex organisms can also be found in the mitochondria. This DNA is called mitochondrial DNA (mtDNA). WebGenomic DNA is tightly and orderly packed in the process called DNA condensation, to fit the small available volumes of the cell. In eukaryotes, DNA is located in the cell nucleus, with small amounts in mitochondria and chloroplasts. In prokaryotes, the DNA is held within an irregularly shaped body in the cytoplasm called the nucleoid. floral painters artists
