A nucleoprotein is any protein that is structurally associated with nucleic acid[1] (either DNA or RNA).

Many viruses harness this protein, and they are known for being host-specific. That is, they find it difficult to infect species besides the ones they normally infect.


The prototypical example is any of the histone class of proteins, which are identifiable on strands of chromatin. Telomerase, a RNP (RNA/protein complex), and Protamines are also nucleoproteins.
