DNA Computing

What Does DNA Computing Mean?

DNA computing is the use of biomolecular components rather than standard artificial hardware (such as silicon chips) in computer technology. In place of traditional code (such as the common binary variety), DNA computing utilizes the four-character genetic alphabet, which consists of:

Techopedia Explains DNA Computing

American physicist Richard Feynman introduced the idea of biomolecular computation in 1959 when presenting research on nanotechnology. However DNA computing was not put into practice until 1994, when American computer scientist Leonard Adleman created a system of algorithmic processes in DNA sets.

Although the practice has inspired a great deal of interest among science and technology circles, DNA computing has never been implemented on any broad scale, as its processing is considerably less efficient than that of standard hardware configuration.
