The interaction of the metal atom with guanine and uracil has been analyzed using the B3LYP density-functional approach. The removal of one electron from the neutral complexes produces the stabilization of one of the isomers, while the addition of one electron leads to a system where the metal atom is weakly bounded to guanine or uracil, according to the metal-bases bond distance that is long (2.29-2.90). For guanine-Cu and uracil-Cu, the vertical ionization energy of the anion is close to the dissociation energy of one hydrogen atom from guanine-Cu or uracil-Cu. In these cases, it could be possible to pro
