question 1

Multiple Choice

Which of the following statements most accurately describes general features of inducible and repressible systems for the negative control of transcription of an operon?

• A) Repressor protein is bound to the operator region in the absence of small effector molecules in both inducible and repressible systems.
• B) Repressor protein does not bind to the operator region when specific small effector molecules bind to the repressor protein in both inducible and repressible systems.
• C) Repressor protein binds to the operator in repressible systems only after binding co-repressor, whereas repressor protein from inducible systems binds to operator only in the absence of an inducer.
• D) Inducers are end products of the biosynthetic sequence which they control, whereas co-repressors are substrates for the catabolic metabolic pathways that they control.
• E) Inducible systems in prokaryotes are generally positively controlled at the transcriptional level, whereas repressible systems are negatively controlled at the transcriptional level.
