Question

An inactive repressor produced by regulator gene that does not block the operator site in the tryptophan Operon is called​

Answer 1

Answer:

Low tryptophan: trp repressor is not bound to tryptophan (since there is no tryptophan) and is thus in its inactive state (does not bind to the DNA of the operator). This allows RNA polymerase to bind to the promoter and transcribe the operon. In this system, the trp repressor acts as both a sensor and a switch.
