Abstract	We report the details of the direct electrical transport through 60 base pairs of poly(G)-poly(C) DNA molecules between two electrodes with nanometer spacings. An almost monotonic increase in the current is observed from the sample with the gap of 30 µm and with a DNA solution droplet. The I-V and the dI/dV-V measured from various samples with the electrode gap ranging from 20 to 100 nm at different conditions show reproducible clear staircases. The average gap value of the observed staircases is consistent with the energy gap obtained from a tight binding calculation.
