WHAT IS DNA COMPUTER?
A nanocomputer that uses DNA (deoxyribonucleic
acids) to store information and perform complex calculations. Also known as
parallel processing
HISTORY?
- In 1994, University of Southern California
computer scientist Leonard Adelman suggested that DNA could be used to solve
complex mathematical problems.
- Adelman found a way to harness the power of
DNA to solve the Hamiltonian path problem (the traveling salesman problem),
whose solution required finding a path from start to end going through all the
points (cities) only once.
- Each city was encoded as its own DNA sequence
(DNA sequence consists of a series of nucleotides represented by the letters A,
T, G, C).
- The DNA sequences were set to replicate and
create trillions of new sequences based on the initial input sequences in a
matter of seconds (called DNA hybridization). The theory holds that the
solution to the problem was one of the new sequence strands. By process of
elimination, the correct solution would be obtained.
BENEFIT?
- cheap
- energy-efficient resource.
