| Abstract: | A double helix model of charge transport in DNA molecule is givenand the transmission spectra of four DNA sequences are obtained. Thecalculated results show that the transmission characteristics of DNA are not only related to the longitudinal transport but also to the transversetransport of molecule. The periodic sequence with the same composition hasstronger conduction ability. With the increasing of bases composition, theconductive ability reduces, but the weight of θ direction rises incharge transfer. |
