A first-principle investigation using the recently developed M05-2X density functional and the 6-311++G(d, p) basis set was performed to understand the nature of interaction between C(60) and nucleic acid bases and the Watson-Crick base pairs. It was found that C(60) forms stacking complexes with nucleic acid bases and base pairs. It was revealed that the strength of interaction of nucleic acid bases with C(60) follows the order: G > C > A > T > U, while the GC base pair forms stronger complex than the AT base pair with C(60).
