The L-arabinose operon in an E. coli strain contains genes that code for enzymes used to break down the sugar L-arabinose. A regulatory gene located upstream from the operon encodes the regulatory protein AraC. AraC undergoes a conformational change when it binds to L-arabinose, and this form of AraC binds to the operator site of the operon, acting as an activator, to stimulate RNA polymerase to begin transcription. Explain whether this is an example of positive or negative control and how this compares to the control mechanism of the lac operon.
