David vs. Goliath? More like Methyl vs. Machine! That tiny methyl group (CH3) can shut down gene transcription faster than you can say "epigenetic modification." RNA polymerase might be a massive molecular factory with hundreds of amino acids working overtime, but add one methyl group to cytosine and suddenly it's like putting up a "CLOSED FOR BUSINESS" sign on your DNA. Nature's ultimate power move is just slapping a tiny chemical group on a base and telling the transcription machinery to go home. Size really doesn't matter in molecular biology!
