Name negatively and positively charged components of nucleosome.
A nucleosome is composed of histone protein and DNA. DNA carries the negative charge due to the phosphodiester linkage and histone is basic in nature and carries a positive charge because histones are made up of basic amino acids. DNA wrapped around the histone octamer (H2A-H2B, H3, H4 two copies of each) through the H- bonding. So, the negatively charged component of the nucleosome is DNA and the positively charged components of nucleosomes are histone octamer.
