The most complex biochemical circuit ever created from scratch using DNA-based devices in a test tube has been built by researchers at the California Institute of Technology (Caltech). To build their circuits, the researchers used pieces of DNA to make logic gates. Instead of depending on electrons flowing in and out of transistors, DNA-based logic gates receive and produce molecules as signals. The molecular signals travel from one specific gate to another, connecting the circuit as if they were wires. The new logic gates are made from pieces of either short, single-stranded DNA or partially double-stranded DNA, in which single strands stick out like tails from the DNA's double helix. The single-stranded DNA molecules act as input and output signals that interact with the partially double-stranded ones. All the logic gates have identical structures with different sequences. |
