Question

In the regulation of the arabinose operon, arabinose binding alters the conformation of the dimerization domain of the AraC protein.

a. true
b. false

Answer 1

In the regulation of the arabinose operon, arabinose binding alters the conformation of the dimerization domain of the AraC protein.

Step-by-step explanation:

True. In the regulation of the arabinose operon, arabinose binding alters the conformation of the dimerization domain of the AraC protein.

This conformational change allows the protein to bind to the initiator site, promoting transcription of the genes involved in arabinose metabolism.
