Cell Cycle and Division
Interphase in the Cell Growth Cycle
Description
Interphase is the stage of the cell cycle when a eukaryotic cell grows and copies its DNA before mitosis. In a typical human cell, the full cell cycle takes about 24 hours, and interphase makes up about 95 percent of that time. It is followed by mitosis, also called M, when the cell divides.

在真核细胞中
细胞周期的最长的部分是分裂间期
它分为三个阶段G1 S和G2
G1 第一个间隙期
新生成的子细胞大小增加
并下一阶段DNA复制做准备
S期 合成期
细胞复制核DNA
仍然包装为染色质
细胞还复制中心体
即微管组织结构
其形成有丝分裂纺锤体
最终 G2 第二个间隙期
细胞继续生长 繁殖细胞器
和有丝分裂所需的蛋白质
并补充其能量储备
细胞现在已准备好进入有丝分...
