Programming a DNA Clock
February 22, 2018
(Scientific American) – Nature is a master at constructing biological machines and circuits, including the ones that maintain the body’s internal clock, copy genes or help cells move. Now human engineers are learning to design and synthesize novel biochemical devices such as nanoscale factories, biological circuits and even molecular computers. This work has so far relied mostly on using existing cellular components (enzymes, for example), but some researchers prefer to start from scratch.
