I found the exercise on the internet. Attached is a picture of the <span>statements and the bins.
Operon is not transcribed:
-trp operon: tryptophan present (tryptophan works as an inhibitor of the operon)
-lac operon: lactose absent (lactose works as the trigger for the operon)
Operon is transcribed but not sped up by positive control:
-trp operon: tryptophan absent </span>(tryptophan works as an inhibitor of the operon, when absent the operon is active)
-lac operon: lactose present, glucose present (lactose works as the trigger for the operon, but when glucose is present, the operon activity remains only at basal level)<span>
Operon is transcribed quickly by positive control:
-lac operon: lactose present, glucose absent </span>(lactose works as the trigger for the operon, but when glucose is absent, the operon activity is at its maximum activity)
Operon is not transcribed:
-trp operon: tryptophan present (tryptophan works as an inhibitor of the operon)
