The correct answer would be mitosis or M phase.
Mitosis or M phase is the phase of the cell cycle during which the actual division of the cell takes place that is, the division of nuclear content. It is also termed as karyokinesis.
It is primarily divided into four stages:
- Prophase
- Metaphase
- Anaphase
- Telophase.
It results in the equal distribution of chromosomes into two daughter cells.
It is followed by cytokinesis by which cytoplasmic content is equally divided into the two daughter cells.
