Deoxyribonucleoprotein

Deoxyribonucleoprotein (DNP) is the complex of DNA and protein in which DNA is usually found upon cell disruption and isolation.

The most widespread deoxyribonucleoproteins are nucleosomes, in which the component is nuclear DNA. The proteins are combined with DNA are histone]s and protamines; resulting nucleoproteins are located in chromosomes. Thus, the entire chromosome, i.e. chromatine material in eukaryotes] consists of such nucleoproteines.
