Cytokinesis usually, but not always, follows mitosis. If a cell completes mitosis but not cytokinesis, the result would be a cell with:
Correct answer: D. Two nuclei
- A. A single large nucleus
- B. High concentrations of actin and myosin
- C. Two abnormally small nuclei
- D. Two nuclei
Explanation
If a cell completes mitosis but not cytokinesis, the result would be a cell with two nuclei. This condition is known as "cellular multinucleation." Essentially, the genetic material has been segregated into two separate nuclei, but the cytoplasm has not been divided into two distinct daughter cells. As a result, the cell will have multiple nuclei within a single cytoplasmic compartment. This can be observed in certain types of cells, such as muscle cells and some fungi.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
