lol pls tell me ur joking Maria

The lac operon has a single promoter. The genes encode proteins that allow the bacteria to use lactose for energy.

Why would the lactose operon be switched on in the presence of glucose? There is already a source of energy, you fucking idiot.

This is basic biochemistry. Why the fuck would the operon be activated, does that make any sense?!??

I’m not ashamed to admit I’m a casual.

My baby brother is really into basketball, he’s like a D1 prospect and shit. So I just come on here to stay updated, that way I can have a little more in common with him.
