Controlled manipulation of single DNA molecules has enabled direct measurements of electrical transport through the DNA. Experiments on electrical transport through dry and wet DNA molecules revealed a variety of results: DNA has been reported to demonstrate proximity-induced superconducting, metallic, semiconducting and insulating behavior. The observed differences are believed to be related to contact effects, the environment of the DNA molecule and the sequence of nucleotides. We use a tight-binding ladder model with a minimal set of adjustable parameters to describe the main features of carrier transport and optically induced electronic transitions in synthetic poly(G)-poly(C) DNA.
