Not possible now because it is not available in shops. It is a future reality that may emerge as DNA based microprocessor. DNA based computing is an emerging technology using the biomolecule DNA as the data storage molecule. It is possible since DNA is doing data storage in the form of genetic information. If DNA computers emerge, it can store billions of times more data than the present computer. The DNA molecule of genes has the potential to perform calculations many times faster than the present microprocessors. By using the Nanotechnology, it is possible to create Nano computers to replace the Silicon based computers.
The idea of DNA computer came from Leonard Adelman, a computer scientist at the University of South California in 1994 to solve complex mathematical problems. The first DNA computers are unlikely to feature word processing, e-mailing and solitaire programs. Unlike conventional computers, DNA computers perform calculations parallel to other calculations. Conventional computers operate linearly, taking on tasks one at a time. It is parallel computing that allows DNA to solve complex mathematical problems in hours, whereas it might take electrical computers hundreds of years to complete them.
DNA Computing is the computational technology that uses the biomolecule DNA in the place of silicon based chips.DNA computing is otherwise known as the Bio molecular computing and is a fast growing interdisciplinary field that uses molecular biology and computer techniques in research and bio informatics areas.
The DNA computing technique was developed by Leonard Adleman of the University of South California in 1994.In 2002 a programmable bio computing machine was developed using DNA as the major element. In 2004, a DNA computer was designed to study the changes in cancerous cells. In 2009 a bio computer coupled with silicon chips was introduced which was based on enzyme systems and silicon chips. This marked great advancement in the field of Synthetic biology to use integrated systems of biological molecules and electronic chips.
