Question:
Choose the incorrect statement of the following:
Choose the incorrect statement of the following:
Show Hint
Promoter = Initiation site (Polymerase binds here).
Updated On: Jun 6, 2026
- Operator is the region of DNA where RNA polymerase binds and initiate transcription
- A group of closely placed structural genes and regulatory element is called promoter
- Process of turning genes on and off so that appropriate genes are expressed. This phenomenon is called gene regulation
- Heterogenous nucleus RNA present in nucleus which becomes mRNA is called hn RNA
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Molecular genetics and operon models.
Step 2: Meaning
Identifying definitions within gene expression regulation.
Step 3: Analysis
The promoter is the region where RNA polymerase binds to initiate transcription, not the operator. The operator acts as a switch, not the binding site for the polymerase itself.
Step 4: Conclusion
The statement identifying the operator as the binding site is incorrect.
Final Answer: (A)
