Researchers from the University of Sydney have developed a system that mimics natural selection inside living mammalian cells but in a very controlled setting. They call it PROTEUS, short for PROTein ...

Schematic of the T7-ORACLE system. The genome is maintained by the non-mutagenic host replisome (gray), while an orthogonal T7 replisome (red) maintains only a dedicated plasmid (OR) at 100,000-fold ...
