"WebMPF provides a good example of how cyclins and Cdks can work together to drive a cell cycle transition. Like a typical cyclin, M cyclin stays at low levels for much of the cell cycle, but builds up as the cell approaches the G 2 _2 2 start subscript, 2, end subscript /M transition. As M cyclin accumulates, it binds to Cdks already present in the cell, forming … " - Explain the different phases of cell cycle
