Synthetic Biology Puts A Leash On GMOs
By rewriting the DNA of Escherichia coli so that the bacterium requires a synthetic amino acid to produce its essential proteins, two research teams may have paved the way to ensuring that genetically modified organisms (GMOs) don’t escape into the environment. The life-or-death dependence of the newly engineered E. coli on synthetic amino acids makes it astronomically difficult for the GMO to survive outside the laboratory, explains Harvard Medical School’s George . . .
