DNA is not only a carrier of genetic information, but it is also a versatile supramolecular scaffold, arranging smaller organic structures into predesigned geometries. Herein are discussed molecular strategies in which the natural DNA bases on the sugar-phosphate backbone are replaced by other molecules. Some of the base replacements under study include fluorophores, ligands for metals, helix stabilizers, and DNA base shape mimics.
