Abstract

A one-dimensional model with time-dependent random hopping is proposed to describe charge transport in DNA. It permits the investigation of both diffusion of electrons and their tunneling between different sites in DNA. The tunneling appears to be strongly temperature-dependent. Observations of a strong (exponential) as well as a weak distance dependence of the charge transfer in DNA can be explained in the framework of our model.
