Cell Cycle and Division
Cell Cycle Checkpoints and Cancer
Description
The cell cycle is the set of steps a eukaryotic cell follows as it grows and divides. In somatic cells, it has two main stages: interphase and the mitotic phase. During interphase, the cell grows, carries out its basic metabolic functions, copies its DNA, and gets ready for mitotic cell division.

细胞周期是指
整个细胞典型生命中的事件序列
包括生长
DNA复制 有时更多的生长和分裂
对于有性繁殖的生物
生命始于受精卵
随着时间的推移 原来的单细胞
以受控的方式生长和分裂
产生多细胞复合体
细胞继续这个过程
特别是在衰老过程中
维持和修复组织
相比之下 像细菌这样的单细胞生物
依靠细胞分裂
来简单地通过二分裂进行繁殖
不幸的是 当细胞分裂未经检查时
癌症产生 就会导...
