How do bacteria avoid wasteful production of unnecessary proteins when their genes are always on? The answer lies in regulating the operon. As trp levels increase, trp binds to trpR, causing a ...

The genes and important sequences for the regulation of the lac operon are organized such that several mediators can fine tune expression of the three genes in the operon itself— lacZ, lacY, and lacA.

The 92-year-old bacterial geneticist who helped pioneer the study of gene regulation has passed away. The organizers of the American Diabetes Association meeting had a group of researchers removed ...
