Before mitosis can occur, DNA replication must occur. This DNA replication results in 2 identical copies of the DNA joined at the centromere. During Anaphase of mitosis, these identical copies of DNA, called opposite poles of the cell. are pulled apart to ( genes gametes O sister chromatids daughter chromatids.
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:
Introduction :-
Mitosis is a kind of cell division in which one cell (the mother) divides to generate two genetically identical new cells (the daughters). Mitosis is the stage of the cell cycle's division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
