(G-H)*-C and G-(C-H)* radicals derived from the guanine.cytosine base pair cause DNA subunit lesions.

Abstract

The radicals generated by the homolytic cleavage of an X-H bond from the guanine.cytosine (G.C) base pair were studied by using carefully calibrated theoretical methods. The gradient-corrected density functional B3LYP was applied in conjunction with double-zeta plus polarization and diffuse function basis sets. Optimized geometries, energies, and… (More)
