Metal-Ion Selectivity of Chemically Modified Uracil Pairs in DNA Duplexes

DNA duplexes containing 5-modified uracil pairs (5-bromo, 5-fluoro, and 5-cyanouracil) bind selectivity to metal ions. Their selectivity is sensitive to the pH value of the solution (see picture), as the acidities of the modified uracil bases vary according to the electron-withdrawing properties of...
