Abstract
Charge migration in DNA has been a subject of considerable debate over the last decade. The interior of DNA consist of a stack of aromatic hydrogen-bonded base pairs that resembles a one-dimensional π-conducting structure found in discotic materials (see graphic), but the structure of DNA is highly disordered and fluctuations occur on timescales of pico- to nanoseconds. Here, a theoretical study of the effect of static and dynamic structural fluctuations on the mobility of positive charges along a model B-form poly(G)–poly(C) double helix is presented.
