Solution
The correct option is C MPF-protein kinase
Cell division occurs in defined stages, which together comprise the cell cycle. There are two types of cell division: Meiosis and Mitosis. MEIOSIS: Occurs during formation of the gametes, the number of chromosomes reduced to half in reproductive cellMITOSIS: Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells.MPF- protein kinase promotes the entrance into mitosis (the M phase) from the G2 phase by phosphorylating multiple proteins needed during mitosis. . The MPF is also called the M phase kinase because of its ability to phosphorylate target proteins at a specific point in the cell cycle and thus control their ability to function.
So, the correct option is 'C'.
