Question

difference between inducible and repressible operon​

Answer 1

Answer:

Explanation:

The main difference between inducible and repressible operons is that the inducible operons are turned off under normal conditions while the repressible operons are turned on under normal conditions. ... An operon is a cluster of functionally-related genes regulated under a common promoter.

Answer 2

Answer:

Some operons are inducible, meaning that they can be turned on by the presence of a particular small molecule. Others are repressible, meaning that they are on by default but can be turned off by a small molecule.The main difference between inducible and repressible operons is that the inducible operons are turned off under normal conditions while the repressible operons are turned on under normal conditions. Furthermore, the binding of the inducer to the active repressor of inducible operons causes the inactivation of the repressor and the binding of RNA polymerase to the promoter region while binding of the co-repressor to the inactive repressor of the repressible operons causes the activation of the repressor, which prevents the binding of the RNA polymerase to the promoter region.

Inducible and repressible operons are two types of operons in the prokaryotic genome. An operon is a cluster of functionally-related genes regulated under a common promoter. Moreover, lac operon is such an inducible operon while trp operon is a repressible operon.
