The destruction of the various cyclins is commonly used to inactivate the Cdk/cyclin complexes. Why is it advantageous to inactivate these complexes via protein destruction instead of some other method that does not require the re-synthesis of a cyclin protein the next time the cell divides?
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:

Cancer or tumor growth occurs when the cell cycle regulation mechanisms fail to stop the division of cells in a tissue. This uncontrolled growth could lead to benign or malignant tumors. Cells employ several mechanisms to have a check on the cell division.
CDK is the abbreviation for cyclin-dependent kinases. These enzymes function in the regulation of cell cycle progression through various stages.
