Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
In the absence of cdc25 cells would not be able to undergo mitosis.
True or False?
Cell division cycle 25 A (Cdc25A) is a dual-specificity protein phosphatase which is a crucial cell cycle regulator.
uncontrolled cell proliferation, as in cancers, is primarily due to deregulation of the cell cycle.
CDKs are cell cycle regulators that phosphorylate to activate consequent retinoblastoma protein so as to promote progression in the cell cycle. however, it also needs tight controlling which is brought about by Cdc25 phosphatase which dephosphorylates CDKs which lifts the inhibition of these molecules.
