The Cell Cycle: Cell Cycle Regulation SparkNotes

WebJan 24, 2024 · A Cell Cycle is the series of events that occur in a cell that includes the division and growth of a cell. The division of a mother cell into two or more daughter cells is known as Cell Division. Cell division is the key to growth, repair, and reproduction. Every dividing cell is called a mother cell, and its descendants are named daughter cells. WebIn short, Cyclin B+ CDK= MPF and MPF+ phosphate= active MPF.
