Introduction:
A nanocomputer that uses DNA (deoxyribonucleic acids) to store information and perform complex calculations.
DNA computers are the computers which using enzymes as a programme that processes on the dna molecules(input data)
A DNA computer is basically a collection of specially selected DNA strands whose combinations will result in the solution to some problem.
The promise of DNA computing is massive parallelism: with a given setup and enough DNA, one can potentially solve huge problems by parallel search.
Existing System
Conventional computers are used.
Conventional computers require large amount of hardware.
Proposed System
Proposed system is DNA computer has a great deal of advantage over conventional computers. DNA computers can store billions of times more data than personal computer. DNA computers have the ability to work in a massively parallel fashion, performing many calculations simultaneously.
What is Need?
Computers have become significantly smaller and more powerful over the past 40 years. It would be hard to believe where scientists have found the new material they need to build the next generation of microprocessors. Millions of natural supercomputers exist inside living organisms, including our body.
Interesting Facts:
DNA is the basic medium of information storage for all living cells. It has contained and transmitted the data of life for billions of years.
Roughly 10 trillion DNA molecules could fit into a space. Since all these molecules can process data simultaneously, you could theoretically have 10 trillion calculations going on in a small space at once.
Dense Information Storage:
This image shows 1 gram of DNA on a CD. The CD can hold 800 MB of data.
The 1 gram of DNA can hold about 1x1014 MB of data.
The number of CDs required to hold this amount of information, lined up edge to edge, would circle the Earth 375 times, and would take 163,000 centuries to listen to.
Conclusion:
DNA computers use cheap, clean, and readily available materials, they store more information in less space, and especially that they can handle massive parallel processing.
