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.
Proteins of DNA Replication. DNA exists in the nucleus as a condensed, compact structure. To prepare DNA for replication, a series of proteins aid in the unwinding and separation of the double-stranded DNA molecule. These proteins are required because DNA must be single-stranded before replication can proceed.
