Question

Which one of the folowing is not true of the attenuation that controls gene expression?

• A. It is seen in tryptophan operon
• B. It is a mechanism whereby transcription is controlled before the initiation of of the mRNA synthesis
• C. Attenuation depends on the stem and loop structures in the mRNA
• D. In eukaryotes, there is no exact equivalent of attenuation as transcription and translation are spatially separated.

Hint:

Remember: Promoter regulation controls transcription initiation, while attenuation controls transcription termination (elongation).
