WebG2/M checkpoint; metaphase checkpoint (spindle checkpoint) G1 Checkpoint. It is a restriction point in mammalian cells and the start point in yeast. It is the main decision point for a cell i.e., the primary point at which it must choose whether to divide or not. As the cell continues through G1, it can either delay G1, enter G0, or proceed ... The G2-M DNA damage checkpoint is an important cell cycle checkpoint in eukaryotic organisms that ensures that cells don't initiate mitosis until damaged or incompletely replicated DNA is sufficiently repaired. Cells with a defective G2-M checkpoint will undergo apoptosis or death after cell division if they enter the M phase before repairing their DNA. The defining biochemical feature of this che… cinnamon rolls pudding
