Genetic toggle switch and repressilator papers

An article published in Nature reports the first genetic circuits had been engineered to carry out designed functions using a genetic toggle switch. Cells that harbored the circuit could toggle between two stable expression states in response to external signals.

With the repressilator, activation of an oscillatory circuit resulted in the ordered, periodic oscillation or repressor protein expression.

These studies combined quantitative design, physical construction, experimental measurement, and hypothesis-driven debugging to construct synthetic circuits, which became a characteristic feature of constructing synthetic circuits.

Nobel Prize in Physiology or Medicine for the discovery of restriction enzymes

Werner Arber, Daniel Nathans, and Hamilton Smith share the 1978 Nobel Prize "for the discovery of restriction enzymes and their application to problems of molecular genetics." A November 1978 editorial in Gene states, "The work on restriction nucleases not only permits us easily to construct recombinant DNA molecules and to analyze individual genes but also has led us into the new era of 'synthetic biology' where not only existing genes are described and analyzed but also new gene arrangements can be constructed and evaluated.
