Lac operon Memes

The epic battle of cellular regulation, starring Piccolo as the repressor protein! He's literally blocking a whole jar of spaghetti (RNA polymerase) from reaching tiny Gohan (DNA transcription). This is exactly how the lac operon works - repressor proteins physically block RNA polymerase from transcribing genes until lactose shows up and tells the repressor "hey buddy, take five." Biology's version of "you shall not pass" but with more molecular drama and fewer wizards.
