The combination of the self-assembly and electronic properties as well as its true nanoscale dimensions makes the DNA a promising candidate for a building block for single molecule electronics. We argue that the intrinsic double helix conformation of the DNA strands provides a possibility to control the electric current through the DNA by a perpendicular electric (gating) field and demonstrate the transistor effect for the gated double-stranded poly(G)-poly? synthetic DNA, using a simple model approach. Experimental set-ups to observe the predicted effect will be also discussed. In addition, we propose a design of a single molecule analog of the Esaki diode.
