Scientists have developed the biological equivalent of a transistor.
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. The findings were reported today (March 28) in the journal Science.
