Regulation Mechanism Description A. Negative Regulation 1. Induction by lactose or allolactose B. Positive Regulation 2. Inhibition by the repressor protein C. Inducer 3. Substance that inactivates the repressor D. Repressor Protein 4. Regulates transcription by binding to the operator
Options
- AA - 2, B - 1, C - 3, D - 4
- BA - 1, B - 2, C - 4, D - 3
- CA - 2, B - 3, C - 1, D - 4
- DA - 4, B - 1, C - 2, D - 3
Correct answer
A. A - 2, B - 1, C - 3, D - 4
Step-by-step solution
A - 2: Negative Regulation refers to the inhibition by the repressor protein. B - 1: Positive Regulation involves induction by lactose or allolactose (though not covered in this text). C - 3: Inducer is a substance that inactivates the repressor. D - 4: Repressor Protein regulates transcription by binding to the operator.
