    Q:

    		 A new inducer-receptor interaction shows that the inducer activates the transcription of certain genes only once a high-concentration threshold of inducer concentration is reached. The presence of a high concentration threshold implies what about the mechanism of inducer-receptor interaction?
    		 

    A

    		 strong binding interaction

    B

    		 weak binding interaction

    C

    		 negative feedback loop

    D

    		 inhibition of the receptor
