Gene regulation Memes

The p53 protein doesn't mess around when it spots cellular abnormalities. It's basically the quality control supervisor that will absolutely terminate a cell's existence if it detects DNA damage during mitosis. The protein literally activates apoptosis—programmed cell death—like it's firing an employee who showed up drunk to work. "I'm about to end this man's whole career" is exactly what p53 would say if proteins could talk. No warnings, no second chances, just straight to cellular suicide. Nature's most ruthless bouncer.
