Some cells have several nuclei per cell. How might such multinucleated cells arise?
A) repeated mitosis with concomitant cytokinesis
B) multiple S phases before the entry of a cell into mitosis
C) repeated mitosis without cytokinesis
D) repeated cytokinesis with no mitosis

Question

Quizplus · Accepted Answer

Multinucleated cells can occur when a cell undergoes repeated rounds of mitosis without cytokinesis. This is also known as incomplete cytokinesis. Instead of dividing into two separate daughter cells, the cell's nucleus undergoes mitosis multiple times within the same cytoplasmic space, resulting in multiple nuclei within a single cell. This process can occur naturally during development or tissue repair, or it may be induced by certain drugs or environmental factors.
