Electron localization lengths in different DNA sequences have been calculated numerically using the transfer matrix method. It is shown that electronic states associated with guanine can reach fairly long localization lengths in disordered guanine-cytosine double strands if both intra- and interstrand π−π interactions are considered. For DNA sequences containing all four bases, the electronic states become localized to very few base pairs. In particular, the human chromosome 22 and λ-DNA, both with approximately equal concentrations of the four bases, show insulating behavior.
