Describe DNA Damage: Definition: Define DNA damage. What are some causes of DNA damage? What affect does DNA damage have? Will replication proceed normally? If DNA damage is      not repaired, what affect will it have? Can DNA damage be repaired? If DNA damage is not repaired, what affect will it have on the cell cycle (cell division)

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:
