Attenuation in the Trp Operon of E. Coli

question 11

Multiple Choice

Attenuation in the trp operon of E. coli:

• A) can adjust transcription of the structural genes upwards when tryptophan is present.
• B) can fine-tune the transcription of the operon in response to small changes in Trp availability.
• C) is a mechanism for inhibiting translation of existing (complete) trp mRNAs.
• D) results from the binding of the Trp repressor to the operator.
• E) results from the presence of short leader peptides at the 5' end of each structural gene.
