Multiple Choice
Which part of the cell cycle directly results in the formation of two daughter cells?
A
Prophase
B
S phase
C
Metaphase
D
Cytokinesis
Verified step by step guidance
1
Understand the cell cycle: The cell cycle consists of interphase (G1, S, and G2 phases) and the mitotic phase (M phase), which includes mitosis and cytokinesis.
Review the role of cytokinesis: Cytokinesis is the final step of the M phase, where the cytoplasm divides, resulting in the physical separation of the parent cell into two daughter cells.
Differentiate between mitosis and cytokinesis: Mitosis involves the division of the nucleus and its genetic material, while cytokinesis involves the division of the cytoplasm and cell membrane.
Analyze the options: Prophase and metaphase are stages of mitosis, and the S phase is part of interphase where DNA replication occurs. None of these directly result in the formation of two daughter cells.
Conclude that cytokinesis is the correct answer because it is the process that directly leads to the formation of two separate daughter cells by dividing the cytoplasm and completing cell division.
