Answer:
The correct answer is option a. "Transcription would not occur at high levels in either the presence or absence of arabinose".
Explanation:
The ara operon, also known as the L-arabinose operon, is a series of related genes that are transcribed within the same transcript and are all related to the metabolism of L-arabinose. Among the proteins translated from the ara operon, the AraC protein that binds to RNA Polymerase is the one that recognizes L-arabinose and enhances ara operon transcription in its presence. Therefore, if a mutation removes the gene that encodes for the AraC protein, transcription would not occur at high levels in either the presence or absence of arabinose.
