WebJan 10, 2024 · Furthermore, Cu-phendione exhibited the lowest concentration that inhibits 50% fluorescence (Q EtBr = 100.7 μM and Q Hoechst = 66.0 μM), which suggests that this compound has a dual-mode of interaction with DNA, being able to intercalate into the compact array of stacked bases as well as partially groove bind to the DNA. WebIn biochemistry, intercalation is the insertion of molecules between the planar bases of deoxyribonucleic acid (DNA). This process is used as a method for analyzing DNA and it is also the basis of certain kinds of poisoning. Ethidium intercalated between two adenine-thymine base pairs. There are several ways molecules (in this case, also known ...
