Gene-OFF switches tool up synthetic biology

Researchers have developed two types of programmable repressor elements that can switch off the production of an output protein in synthetic biology circuits by up to 300-fold in response to almost any triggering nucleotide sequence. The researchers combined up to four repressor elements in universal NAND (NOT-AND) and NOR (NOT-OR) gates in complex molecular logic boards.
