In bacteria, genes of related function are grouped together as operons. These operons may either be inducible or repressible. Inducible operons are usually turned off while the repressible operons are usually turned on and both are only switched on/off with the appropriate signals.
If the lac repressor were altered so it could not release lactose once lactose was bound to it then you would predict that:
A. The repressor could not bind to DNA.
B. The repressor would always be bound to DNA.
C. The repressor could bind to DNA only when cells were grown with glucose.
D. The repressor could bind to DNA only when cells were grown without glucose.
