Abstract
We investigate the effect of helix angles on polaron motion in poly-DNA in the framework of a tight binding model. A DNA molecule is supposed to have a uniform or a random distribution of the helix angles. It is found that a polaron moves faster along a DNA molecule with an overwinding helix than that with an unwinding one. In DNA molecule with randomly distributed helix angles, charge transport is suggested to be field-facilitated tunneling between spatial disordered potential wells.
