Caption: Measurements of tunneling current plotted against time for guanine-cytocine base pairs and for adenine-thymine pairs. Tunneling current for A-T pairs persists for a shorter duration, falling off precipitously compared with the same measurements for C-G pairs, which are held together with 3 hydrogen bonds.
