The main advantage of both methods is that they work reliably (i) for short DNA strands ranging from 13 (DFT studies [37] ) base pairs up to 30 base pairs length which are being used in the nanoscopic transport measurements [15] as well as (ii) for somewhat longer DNA sequences as modelled in the electron transfer results and (iii) even for complete DNA sequences which contain, e.g. for human chromosomes up to 245 million base pairs [2] . The fishbone and ladder models studied in the present paper give qualitatively similar results, i.e. a gap in the DOS on the order of the hopping energies to the backbone, extended states for periodic DNA sequences and localised states for any non-zero disorder strength.	./cache/cord-102359-k1xxz4hc.txt	./txt/cord-102359-k1xxz4hc.txt
