Question
**A partial diploid of the ABC operon is generated by combining the previous genotypes, resulting in the following genotype:** testR- testP+ testO+ test1+ test2- test3+ / testR+ testP+ testO- test1- test2+ test3+ **In this partial diploid, testR+ is [blank] -acting and testO- is [blank] -acting.** *Note:* The two blanks are meant to be filled with information during an educational activity.
Transcribed Image Text:**A partial diploid of the ABC operon is generated by combining the previous genotypes, resulting in the following genotype:** testR- testP+ testO+ test1+ test2- test3+ / testR+ testP+ testO- test1- test2+ test3+ **In this partial diploid, testR+ is [blank] -acting and testO- is [blank] -acting.** *Note:* The two blanks are meant to be filled with information during an educational activity.
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:** 1. **Regulatory Gene (testR):** - Located at the start of the sequence. - Produces a regulatory protein. 2. **Promoter and Operator:** - The promoter is labeled as testP, preceding the operator. - The operator site controls the ability of RNA polymerase to transcribe the operon. 3. **Structural Genes:** - Comprised of test0, test1, test2, and test3. - Responsible for producing structural proteins. 4. **Gene Functions:** - The test0 gene is directly downstream of the operator. - test1, test2, and test3 follow test0 in sequence and contribute to the synthesis of structural proteins. When molecule A binds to the regulatory protein, it triggers the activation of the operon, allowing the structural genes to be transcribed and translated into proteins.
