What is the final outcome of cytokinesis?

Cytokinesis is a crucial part of the cell cycle that occurs at the end of mitosis. Its main purpose is to divide the cytoplasm of a parental cell into two daughter cells, each with its own nucleus and adequate cellular machinery to function independently.

During cytokinesis, the cell membrane is pinched inwards to form two distinct cells. This process ensures that each daughter cell receives a share of the cytoplasm and organelles from the parent cell, thus effectively completing cell division.

The other options relate to different processes that occur either prior to or during cell division. The formation of the mitotic spindle pertains to the organization of chromosomes for separation, alignment of chromosomes deals with preparing them for segregation, and repair of DNA involves ensuring that genetic material is intact before cell division occurs. None of these describe the concluding stage of separating the cell into two individual entities, which is the essential role of cytokinesis.
