DNA Computer Solves a Complex Problem

Posted by Dale on Mar 18, 2002 at 09:44

A DNA-based computer has solved a logic problem that no person could complete by hand, setting a new milestone for this infant technology that could someday surpass the electronic digital computer in certain areas.

The idea was to use a strand of DNA to represent a math or logic problem, and then generate trillions of other unique DNA strands, each representing one possible solution. Exploiting the way DNA strands bind to each other, the computer can weed out invalid solutions until it is left with only the strand that solves the problem exactly.


And we already know the answer is 42!!!
