DNA Circuit System and Charge Transfer Mechanism

Abstract

Based on the accurate identification of chemical structures as electric elements, we described charge transport mechanism in a DNA molecule by a stepwise LC oscillatory circuitry, in which every base pair is a capacitor, every phosphate bridge is an inductor, and every deoxyribose is a charge router. The circuit model agrees with established experimental evidence that has supported super-exchange and hopping mechanisms so far. This alternative charge transport mechanism through both strands of DNA matches the fidelity and reliability of its chemical structure.
