Mitosis (or meiosis in sex cells) occurs.
The cell should have already made duplicates of its chromosome, mitosis is basically the alignment and splitting up of these homologous pairs, creating 2 cells with the same number of chromosome.
Mitosis is broken down into 4 phases:
1.Prophase
2.Metaphase
3.Anaphase
4.Telophase
Look these up if you want to know the specifics of each phase.

Yes, replication occurs throughout the life of a cell as part of the cell cycle, allowing the cell to divide and produce new cells.
Most growth in the body occurs because individual cells divide and multiply to increase in number. This process, known as cell proliferation, is essential for tissue growth, organ development, and overall body growth. As cells divide, they also differentiate into specific cell types to perform specialized functions within the body.
The Replication of DNA does occur before the cell can divide.
A cell replicates its entire chromosomal DNA only during the S phase of the cell cycle, which occurs before cell division. This ensures that each daughter cell receives an identical copy of the genetic material.
Most of the cell's life is spent in interphase. The cell increases in size, then replicates its DNA. After some additional growth, the cell is ready to divide. Mitotic division occurs and the two daughter cells each return to interphase. Some cells enter senescence and cease to divide.
Yes, cell division occurs continuously throughout a person's lifetime for growth, repair, and maintenance of tissues. However, the rate of cell division varies among different cell types and decreases with age.
Cells grow and divide at an abnormally high rate in cancer. This uncontrolled growth leads to the formation of tumors.
A cell divide into four sex cells with half of the chromosomes. Meiosis only occurs in the genital with sex cells.
Mitosis occurs in all somatic cells. Examples would include: skin cells, bone marrow, red blood cells, brain cells, etc. This is as opposed to meiosis, which only occurs in gametes (reproductive cells).
During cytokinesis, the final step of cellular division that occurs technically after mitosis, the nuclear membrane re-forms and the cell membrane pinches off.
It occurs in the nucleus of the cell.
