During which phase does the cell actually separate into two individual daughter cells?
Korolek [52]

During the cytokinesis phase of mitosis, the cell actually separates into two individual daughter cells.

The cell truly divides into two daughter cells during cytokinesis. DNA is duplicated at the start of mitosis and starts to condense into chromosomes during prophase. The chromosomes align in the center of the cell during metaphase.

The chromosomes are dragged in opposite directions toward the cell's sides during anaphase. The cell is still whole and complete. The additional nuclei then develop during telophase, but the cells have not yet separated. The new membrane does not totally divide the two daughter cells until cytokinesis.

Following the division of the nucleus, a cell's cytoplasm divides through a process known as cytokinesis.
