Question
In negative operon
Options
A.co- repressor binds with repressor
B.co- repressor does not binds with repressor
C.co- repressor binds with inducer
D.cAMP has negative effect on lac operon
Solution
In case of a repressible operon, the free repressor cannot bind to the operator. Only repressor- corepressor complex binds with the operator Since the product of the regulator (the repressor) acts by shutting off the transcription of structural genes, it is referred to as a negative control system.
