Think of DNA as software, enzymes as hardware and put them together in a test tube. The way in which these molecules undergo chemical reactions with each other allows simple operations to be performed as a byproduct of the reactions.
This idea of using DNA to store and process information took off in 1994 when a California scientist first used DNA in a test tube to solve a simple mathematical problem. Later Israeli scientists devised a computer composed of enzymes and DNA molecules instead of silicon microchips. Now they have gone one step further. The single DNA molecule that provides the computer with the input data also provides all the necessary fuel.

- In general, the DNA computer looks like water solution in a test tube. DNA computing is in its infancy, and its implications are only beginning to be explored. But it could transform the future of computers, especially in pharmaceutical and biomedical applications .
- While a desktop PC is designed to perform one calculation very fast, DNA strands produce billions of potential answers simultaneously.
- In speed and size, DNA computers surpass conventinal computers. This makes the DNA computer suitable for sloving "Fuzzy logic" problems.
- DNA computing research is going so fast that its potential is still emerging. Some scientists predict a future where our bodies are patrolled by tiny DNA computers that monitor our well being and release the right drugs to repair damaged or unhealthy tissue.
