| Abstract: | A double helix model of charge transport in DNA molecule is given
and the transmission spectra of four DNA sequences are obtained. The
calculated results show that the transmission characteristics of DNA are not only related to the longitudinal transport but also to the transverse
transport of molecule. The periodic sequence with the same composition has
stronger conduction ability. With the increasing of bases composition, the
conductive ability reduces, but the weight of θ direction rises in
charge transfer. |
