DNA Computer Shows Programmable Chemical Machines Are Possible
In research reported this week in Nature, computer scientists took a small but important step toward harnessing the potential of chemical computation by constructing the first broadly programmable DNA computer. The computer depends on the fact that single-stranded DNA will try to pair up with other strands having a sequence of chemicals complementary to its own. In order for the computation to progress in an orderly fashion—essentially growing a crystal that computes—the researchers needed something that would act as a starting point and a structure on which the DNA could assemble.
