We find insulating behavior with localizaton lengths xi ~ 25 in units of average base-pair seperation. Furthermore, we observe small, but significant differences between lambda-DNA, centromeric DNA, promoter sequences as well as random-ATGC DNA.4 pages, 1 figure, Proceedings of "Transport in Interacting and Disordered Systems (TIDS11)", accepted for publication in phys. stat. sol.
