Digital Evolution: DNA May Bring Computers to Life

The transistor revolutionized electronics and computing. Now, researchers have made a biological transistor from DNA that could be used to create living computers.

A transistor is a device that controls the flow of electrons in an electrical circuit, which acts as an on-off switch. Similarly, the biological transistor — termed a transcriptor — controls the flow of an enzyme as it moves along a strand of DNA (deoxyribonucleic acid). These cellular building blocks could be used to do anything from monitoring their environment to turning processes on and off in the cells.
