Question
This figure represents the ABC operon, which is a **negative inducible** operon, and its associated regulatory gene. The structural genes produced by the operon convert molecule A into molecule D. When molecule A is present in the environment, it will bind to the regulatory protein, and operon expression will be induced. **Diagram Explanation:** - **Structure:** - The diagram consists of a sequence of genetic elements with labeled components. - **Regulatory Gene:** - Labeled as *testR*. This gene produces a regulatory protein. - **Operon Components:** - **Promoter:** Labeled as *testP*, where RNA polymerase binds to initiate transcription. - **Operator:** A segment adjacent to the promoter, involved in regulating access of RNA polymerase. - **Structural Genes:** Labeled as *test0*, *test1*, *test2*, and *test3*, which encode structural proteins. - **Process:** - The operon includes the sequence from promoter to structural genes, responsible for protein synthesis. - When molecule A binds to the regulatory protein, the operon's expression is triggered, leading to the synthesis of molecules converting A to D.
