While neurons actively use electric currents in the body to relay messages to the brain, the strand of DNA is not alien to the concept of electric conductivity either. Science experiments at the Warwick University of UK have shown that the DNA identifies faulty activity in itself by the change in its conductivity patterns.

The millions of defects which occur within the DNA molecules each day are constantly being corrected by an army of enzymes. This repair work happens as the mechanics get dispatched to the site of the problem based on the mutations which occur. The mutations are identified by the body seeing the change in DNA conductivity of the damaged section.

Think about it like a house alarm which goes off each time the circuits trip or a window or door is opened without disarming the alarm. In a way the DNA conductivity is a similar alarm for the human body.  However even the body’s alarm system is not fool proof.

In case of some mutations the change in conductivity is not enough to trigger a repair alarm leading to defects which may even cause cancer if they persist. Still in many ways the inner workings of the body are as fascinating as the working of the universe outside.
