The DNA molecule is considered as one-dimensional disordered binary system. Its electronic structure is discussed in terms of base pairs′ relative percentage and distribution using the density of electronic states which are calculated by the negative eigenvalue theory. The result shows that the effect of the base pairs′ relative percentage and distribution on the electronic energy state structure is great. In other words, the sequence of the base pairs plays an important role in determining the electronic structure.
