Multiple Choice

Which statement accurately describes the relationship between cytokinesis and mitosis?

Cytokinesis and mitosis are the same process, both referring to nuclear division.

Cytokinesis always begins before mitosis is complete.

Cytokinesis only occurs in prokaryotic cells, while mitosis occurs in eukaryotic cells.

Cytokinesis typically occurs after mitosis, dividing the cytoplasm into two daughter cells.

Verified step by step guidance

Understand the definitions of mitosis and cytokinesis: Mitosis refers to the division of the nucleus and its genetic material into two identical nuclei, while cytokinesis refers to the division of the cytoplasm and the physical separation of the cell into two daughter cells.

Recognize the sequence of events: Mitosis is a multi-phase process (prophase, metaphase, anaphase, and telophase) that ensures the proper segregation of chromosomes. Cytokinesis typically follows mitosis and completes the cell division process.

Clarify the distinction: Mitosis and cytokinesis are separate processes. Mitosis involves nuclear division, while cytokinesis involves cytoplasmic division. They are not the same process.

Address the timing: Cytokinesis usually begins during the late stages of mitosis (often during telophase) but is not complete until after mitosis has concluded.

Confirm the cell type: Both mitosis and cytokinesis occur in eukaryotic cells. Prokaryotic cells do not undergo mitosis; instead, they divide through a process called binary fission.
