The net electric charge on DNA and histones isA. both positiveB. both – InterviewSolution

1.	The net electric charge on DNA and histones isA. both positiveB. both negativeC. Both (a) and (b)D. zero
Answer» Correct Answer - C DNA consists of a nirtogenous base, pentose suger and a phosphate group. DNA has negative change due to the presence of phosphate group `(PO_(4)^(3-))` Histones are rich in the basic amino acid residues lysines and arginines , which carry positive charges in their side chains. Therefore, histones are positively charged.
