Since mitosis is a type of cell division that occurs in somatic cells, we can assume that new skin cells are fromed through mitotic events.
What is mitosis?
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
First occurs duplication, and then the separation into two new cells happens.
Mitosis occurs in only one phase,
- In the prophase, it occurs chromosomes condensation and nuclear membrane breaks.
- During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.
Each chromatid joins with a microtubule of opposites poles.
- In Anaphase, chromatid sisters separate. The bonds that were keeping them together break, and each of them migrate to the opposite poles.
- In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.
- Finally, cytokinesis occurs.
Since this type of cell division occurs in somatic cells, we can assume that new skin cells are fromed through mitotic events.
