The lac operon has three paradoxes

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

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

 How is allolactose synthesized in Repressed state Answer is Leaky Expression
