What is DNA COMPUTING

Microprocessors made of silicon will eventually reach their limits of speed and miniaturization. So
scientists are turning to our own DNA (deoxyribonucleic acid) molecules, the material our genes are made
of, which have the potential to perform calculations many times faster than the world's most powerful
human-built computers.
Leonard Adleman of the University of Southern California is the Father of DNA Computing.
A DNA computer, as the name implies, uses DNA strands to store information and taps the
Re-combinative properties of DNA to perform operations. A small test tube of DNA strands
suspended in as solution could yield millions to billions of simultaneous interactions at speeds —.
in theory— faster than today's fastest supercomputers.DNA computer uses the re-combinative
property of DNA to perform operations. The main benefit of using DNA computers to solve
complex problems is that different possible solutions are created all at once. This is known as
parallel processing. Humans and most electronic computers attempt to solve the problem one
process at a time (linear processing).DNA itself provides the added benefits of being a cheap,
energy-efficient resource.
In a different perspective, more than 10 trillion DNA molecules can fit into an area no
larger than 1cubic centimeter. With this, a DNA computer could hold 10 terabytes of data and
perform 10 trillion calculations at a time.
In a traditional computer, data are represented by and stored as strings of zeros and ones.
With a DNA computer, a sequence of its four basic nucleotides — adenine, cytosine, guanine, and
thymine — is used to represent and store data on a strand of DNA. Calculations in a traditional
computer are performed by moving data into a processing unit where binary operations are
performed. Essentially, the operations turn miniaturized circuits off or on corresponding to the
zeros and ones that represent the string of data.
