The lac operon has three paradoxes

1-If the operon is in a repressed state, how does the inducer enter the cell to start the process of induction

2- If the operon is in a repressed state, how Repressor is removed with allolactose 

3- How is allolactose synthesized in Repressed state Answer is Leaky Expression
