In the Nucleus and the cytoplasm
Meiosis.
Meisois is is the reproduction of the sex cells (sperm and egg), while mitosis is between a regular cell. Another difference is that Meiosis splits into 4 cells, while mitosis splits into 2.
Hope this helps!
G0 phase cells
The mitotic cycle of somatic, or body, cells is responsible for the production of copies of those cells. The mitotic cycle has different phases, each of which involves a different set of physiological changes to the cell. The G0 phase is described as the resting phase of a cell, where no activities relating to cell division are taking place. G0 phase cells remain in this phase their entire lives, so they do not divide. Another example of such a cell is found in red blood cells.
Prophase
During the prophase stage of mitosis, the nucleus seems to disband itself. The nucleolus suspends itself and finally, the nuclear membrane disassembles itself. This is because of the undergoing process of copying and dividing.
Mitosis is a functional cell dividing process that helps the cells repair or rejuvenate itself because of apoptosis and other factors.
Replication of the DNA and cell growth occur during the S-Phase of the cell cycle.
