WebA DNA double helix can be distorted by intercalating agents that are inserted between the stacked base pairs (Fig. 20.16).Intercalating agents are hydrophobic heterocyclic ring molecules that resemble the ring structure of base pairs and include ethidium bromide, acridine orange, and actinomycin D. Insertion of these agents distorts the DNA double … WebJan 19, 2024 · Together, a base, sugar, and phosphate are called a nucleotide.
