Remember all those darwazas from Sudip's class ? Well.. loook out Silicon Valley - Researchers are developing DNA molecules to mimic the logical operations carried out in silicon-based computers as a way to improve biomedical technologies or aid in assembling nano-size building blocks into new materials. In one approach, a series of wells is filled with hairpin-shaped strands of DNA, called gates, which respond to inputs in ways chosen by the designers. A group had already shown that such a system, called a molecular array of YES and AND gates, or MAYA, can play a game of tic-tac-toe restricted to certain moves. (quoted)
The fact that DNA computing works at such a level, considering that the science is still, more or less, in its infancy, is proof of the immense potential of the subject.
