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 ...

In their landmark 1961 paper on the lac operon, Nobel laureates François Jacob and Jacques Monod speculated that RNA might control gene activity in bacteria through base-pairing interactions. But once ...
