Smart DNA: Programming the Molecule of Life for Work and Play

November, 2008 in Biology

DNA molecules can act as elementary logic gates analogous to the silicon-based gates of ordinary computers. Short strands of DNA serve as the gates’ inputs and outputs.

Ultimately, such gates could serve as dissolved “doctors”—sensing molecules such as markers on cells and jointly choosing how to respond.

Automata built from these DNA gates demonstrate the system’s computational abilities by playing an unbeatable game of tic-tac-toe.
