Histones are the major proteins involved in this packaging. 1  The binding of the chromosomal DNA to histones is the first level of packaging. 2  The DNA-histone protein complex is called the chromatin. 3  There are 5 types of histones namely, H1, H2A, H2B, H3 and H4. The DNA-histone protein complex is called the chromatin. 2  There are 5 types of histones namely, H1, H2A, H2B, H3 and H4. 3  These are basic proteins (25% of basic amino acids lysine and arginine) and negatively charged DNA (due to the presence of phosphate group) can easily bind to these positively charged proteins.
