Abstract

The effect of an external electric field on quantum tunneling in DNA was examined. Zero field potentials for various extensions of the G-C base were first calculated. The change in each of these potentials for three different electric fields was then obtained. To find out if quantum tunneling would be increased with increasing electric field the 3.50 A extension was selected and energy levels tunneling times were calculated for it. Upon comparing the tunneling times at the first tunneling levels for the three fields it was found that an increasing electric field did increase the tunneling rate.
