Question:
Which one of the following is not a part of lac operon?
Which one of the following is not a part of lac operon?
Show Hint
The lac operon serves as an inducible system, typically inactive but can be activated when an inducer like lactose is present.
Updated On: Feb 28, 2025
- Promoter
- Regulator
- Inducer
- Operator

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The lac operon is composed of structural genes, a promoter, an operator, and a regulatory gene. It is activated when a molecule such as allolactose binds to and inactivates the repressor, thereby facilitating gene expression. However, this inducer is not an integral structural component of the operon itself.
