Researchers perform DNA computation in living cells

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. However, thus far DNA computation events have typically taken place in a test tube, rather than in living cells. NC State chemist Alex Deiters and graduate student James Hemphill wanted to see if a DNA-based logic gate could detect the presence of specific microRNAs in human cells…
