Electrical wire properties of DNA linked to cancer
(PHYSorg.com Chemistry)

One of the biggest helpers in our bodies` ongoing efforts to prevent DNA mutations-mutations that can lead to cancer-is actually rather tiny. Electrons, as it turns out, can signal proteins that repair DNA to patch up DNA damage. More specifically, the movement of electrons through DNA, traveling between repair proteins bound to the double helix, helps our cells scan for mistakes that regularly arise in our DNA.
