The Cell Cycle and its Regulation

Shortcut Guy Regulation

Your cells have to divide when you’re growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can’t have cells just growing willy-nilly! That’s what cancer is, and that’s bad. Luckily, cells obey something called the cell cycle, which is regulated by a variety of signaling molecules, which tell the cell when to divide and when to chill out. Let’s look at the phases […]
