Biological Switch May Offer Better Control of Gene Editing

Researchers at the University of Bath and Cardiff University say they have invented a biological switch that can turn protein expression on at will. The switch enables control of genome editing tools that might one day regulate desired genetic changes through entire populations, they add.The team points out that this new switching method should work for any protein in any species and uses a cheap, non-toxic amino acid as the control switch— the “on” mode requires
