DNA COMPUTING

Introduction:

Man’s thirst for knowledge has driven the information revolution. Human brain, a master processor, processes the information about the internal and external environment and sends signals to take appropriate actions. In nature, such controls exist at every level. Even the smallest of the cells has a nucleus, which controls the cell. Where does this power actually come from? It lies in the DNA. The ability to harness this computational power shall determine the fate of next generation of computing.

DNA computing is a novel technology that seeks to capitalize on the enormous informational capacity of DNA, biological molecules that can store huge amounts of information and are able to perform operations similar to that of a computer, through the deployment of enzymes, biological catalysts that act like software to execute desired operations. The appeal of DNA computing lies in the fact that DNA molecules can store far more information than any existing conventional computer chip. Also, utilizing DNA for complex computation can be much faster than utilizing a conventional computer, for which massive parallelism would require large amounts of hardware, not simply more DNA.
