  Recently, some authors have shown that a DNA molecule produces
electromagnetic signals and communicates with other DNA molecules or other
molecules. In fact, a DNA acts like a receiver or transmitter of radio waves.
In this paper, we suggest a mathematical model for the DNA molecule and use of
its communication to cure some diseases like cancer. In this model, first, by
using concepts from string theory and M-theory, we calculate the energy of a
DNA in terms of interactions between free electrons and bound electrons. We
show that when a DNA is damaged, its energy changes and an extra current is
produced. This extra current causes the electromagnetic signals of a damaged
DNA molecule to be different when compared to the electromagnetic signals of a
normal DNA molecule. The electromagnetic signals of a damaged DNA molecule
induces an extra current in a normal DNA molecule and leads to its destruction.
By sending crafted electromagnetic signals to normal DNA molecules and inducing
an opposite current with respect to this extra current, we can prevent the
destruction of normal DNA. Finally, we argue that the type of packing of DNA in
chromosomes of men and women are different. This causes radiated waves from
DNAs of men and women to have opposite signs and cancel the effect of each
other in a pair. Using this property, we suggest another mechanism to cancel
the effect of extra waves, which are produced by DNAs in cancer cells of a male
or a female, by extra waves which are produced by DNAs in similar cells of a
female or a male and prevent the progression of the disease.
