The nucleoprotein

The nucleoprotein - complex proteins, which are composed of the nucleic acid. Examples of protein components of nucleoproteins are mainly histones and Protamine characterized by low mol. the weight and content of amino acids the main character (arginine, lysine, histidine).
There are deoxyribonucleotide (DNP) - protein complexes with deoxyribonucleic acid (DNA) and ribonucleoprotein (RNP) - protein complexes with ribonucleic acid (RNA).
The nucleoprotein found in the nuclei of cells and organelles in the cytoplasm of all organisms, are the main components of the virus. The biological role of nucleoproteins linked to heredity (see), the biosynthesis of proteins (see) and nucleic acids (see), the processes of growth, development, differentiation of various tissues and organs.
