Mechanism of DNA Charge Transport (IMAGE)
Caption
The mechanism of DNA charge transport has been the focus of intensive investigation, though questions remain. In this graphic, current flowing through stacked Guanine DNA (right-hand side of image) is coherent and much stronger, while hopping behavior through alternating Guanine DNA is weaker (left-hand side of image). Guanine bases are highlighted in red with yellow surroundings. The process may be compared with lightning strikes, which follow different pathways to reach the land.
