उत्तर
The net electric charge on DNA and histones is negative and positive, respectively.
Explanation:
On DNA and histones, the net electric charge is both negative and positive. The presence of phosphate ions in the nucleotides makes the DNA molecule negatively charged. Because lysine and arginine amino acid residues are present, his tones are positively charged.

In prokaryotes, DNA is circular and present in the cytoplasm but in eukaryotes, DNA is linear and mainly confined to the nucleus. DNA or deoxyribonucleic acid is a long polymer of nucleotides. In 1953, the first correct double-helical structure of DNA was worked out by Watson and Crick. Based on the X-ray diffraction data produced by Maurice Wilkins and Rosalind Franklin. It is composed of three components, i.e., A phosphate group, a deoxyribose sugar, and a nitrogenous base. Different forms of DNA are B-DNA, Z-DNA, A-DNA, C-DNA, and D-DNA.
