WebDouble helical structure of DNA was discovered by fiber diffraction technique (Kasai, 2005). Fiber diffraction study of DNA–proflavine complex showed that the interaction of proflavine modifies the structure of DNA but maintains the rod-like nature of it with a decrease in the radius of gyration as the proflavine concentration is increased. WebThe diffraction pattern determined the helical nature of the double helix strands (antiparallel). The outside of the DNA chain has a backbone of alternating deoxyribose …
