Plot of the inverse localization lengths ξ as a function of Fermi energy for the ladder model (Eq. 4) and four DNA sequences as well as for the fishbone model with a poly(dG)-poly(dC) sequence. The data for telomeric DNA has been shaded for clarity. Only every 20th symbol is shown for λ- and random-ATGC DNA. Lines are guides to the eye only.
