大部分真核细胞可以持续进行mitosis,周期性地分裂,因此形成了细胞周期(cell cycle)。细胞周期包括间期(interphase)和分裂期(M phase)。 一、间期(Interphase) Interphase包括G1 phase,S phase,G2 phase。 1. G1phase G1 phase的细胞刚刚完成cytokinesis,体积较小,细胞生长(cell growth);同时合成一些蛋白质和RNA,...

大多数真核细胞能够持续进行有丝分裂，并且呈现出周期性分裂的现象，由此形成了细胞周期(cell cycle)。细胞周期包括间期(interphase)与分裂期(M phase)。在间期，细胞进行一系列准备以迎接分裂阶段。G1、S、G2阶段构成了间期，其中G1阶段细胞完成细胞生长并为DNA复制做准备；S阶段是DNA复制的时期，复制后...

分裂期的mitosis，从前期开始，核膜和核仁消失，染色质形成染色体，随后在中期所有染色体排列在细胞中央。在后期，染色单体分离，移向细胞两极，导致染色体数目翻倍。telophase中，染色体解螺旋，细胞核和细胞质开始重新形成。动物细胞的cytokinesis通过收缩环将细胞一分为二，而植物细胞则通过高尔基体囊泡形成细胞...

The sequence of events that a cell goes through from its origin (birth) to its own division into two daughter cells is called the cell cycle. Cell Cycle Interphase - Interphase: the period between cell divisions; - Interphase is divided into G1 (gap 1), S phase, and G2 (gap 2); ...
In this Tools of the Trade article, Cao (Baskin lab) discusses the development of MARS, which enables mitosis-specific recruitment of enzymes to the plasma membrane, exploiting the cell cycle’s natural regulation of PLEKHA5 phosphorylation. ...
