NEETZoologyMolecular Basis of Inheritance
Component Function A. Repressor Protein 1. Region where RNA polymerase binds to initiate transcription B. Operator 2. Region adjacent to the promoter where repressor proteins bind C. Promoter 3. Protein that binds to the operator to inhibit transcription D. Activator Protein 4. Protein that enhances RNA polymerase activity at the promoter
Options
- AA - 3, B - 2, C - 1, D - 4
- BA - 2, B - 1, C - 4, D - 3
- CA - 3, B - 1, C - 2, D - 4
- DA - 4, B - 2, C - 1, D - 3
Correct answer
A. A - 3, B - 2, C - 1, D - 4
Step-by-step solution
A -3: The Repressor Protein binds to the operator to inhibit transcription. B - 2: The Operator is the region adjacent to the promoter where repressor proteins bind. C - 1: The Promoter is the region where RNA polymerase binds to initiate transcription. D - 4: The Activator Protein enhances RNA polymerase activity at the promoter.
