Chemists from North Carolina State University have performed a DNA-based logic-gate operation within a human cell. The research may pave the way to more complicated computations in live cells, as well as new methods of disease detection and treatment.
Logic gates are the means by which computers "compute," as sets of them are combined in different ways to enable computers to ultimately perform tasks like addition or subtraction. In DNA computing, these gates are created by combining different strands of DNA, rather than a series of transistors.
