In normal cells, p21 ACTS like a brake to block cell cycle progression in the event of DNA damage, preventing the cells from dividing and potentially becoming cancerous.

在正常的细胞中，如果DNA受损，p 21就会像刹车一样阻断细胞周期进程以防止细胞分裂和癌变。

Some small subsets do but most of the cells in your brain don't proliferate and that's because they get trapped at one portion of the cell cycle.

除了很小一部分以外大部分脑细胞不增殖,这是因为,它们停滞于细胞周期的某个阶段

If cells were actively proliferating, that is you had a population of cells that are actively proliferating, they would be going through continuous rounds of the cell cycle.

如果细胞处在活跃增殖状态,就是说有一定数量的,细胞具有增殖活性,它们就会连续地经历细胞周期的各个阶段
