细胞周期检查点(Cell cycle checkpoints)是为了确保细胞在复制过程中的完整性和保真度。真核生物存在四个重要的细胞检查点,分别为G1/S Checkpoint,Intra-S checkpoint,G2/M checkpoint,Spindle assembly checkpoint(SAC)。 G1/S Checkpoint 在生长因子的刺激下,细胞从休眠状态中脱离并进入G1期。这些刺激驱动细胞通过...

S 期延伸至所有的 DNA 都被复制完毕;从S期末直至有丝分裂称为G2期,在此期间细胞有两套完整的二倍体染色体。 细胞周期检查点(Cell cycle checkpoints)是为了确保细胞在复制过程中的完整性和保真度。真核生物存在四个重要的细胞检查点,分别为G1/S Checkpoint,Intra-S checkpoint,G2/M checkpoint,Spindle assembly...
Figure 1. The cell cycle is controlled at three checkpoints. The integrity of the DNA is assessed at the G1checkpoint. Proper chromosome duplication is assessed at the G2checkpoint. Attachment of each kinetochore to a spindle fiber is assessed at the M checkpoint. The G1Checkpoint The G1che...

In order to move from one phase of its life cycle to the next, a cell must pass through numerous checkpoints. At each checkpoint, specialized proteins determine whether the necessary conditions exist. If so, the cell is free to enter the next phase. If not, progression through the cell cy...
