Genes Are Like Dominoes… Here’s Why 🧬🔥 | AP Biology 6.5 Regulation of Gene Expression What if your DNA worked like a giant line of dominoes… just waiting for one push? 👀 In this video, we break down AP Biology Unit 6.5: Regulation of Gene Expression in the simplest (and most satisfying) way possible. From ON/OFF gene switches to operons, enhancers, and epigenetics, you’ll see how one small signal can trigger a massive chain reaction inside your cells — just like dominoes falling one after a
