Deoxyribonucleoprotein (DNP) is the complex of DNA and protein[2] in which DNA is usually found upon cell disruption and isolation.[3][4]

The most widespread deoxyribonucleoproteins are nucleosomes, in which the component is nuclear DNA. The proteins combined with DNA are histones and protamines; the resulting nucleoproteins are located in chromosomes. Thus, the entire chromosome, i.e. chromatin in eukaryotes consists of such nucleoproteins.[5][6]

Many viruses are little more than an organized collection of deoxyribonucleoproteins.
