Multiple Choice
In a typical proliferating eukaryotic cell, which part of the cell cycle is generally the longest?
A
Cytokinesis
B
Interphase (G1, S, and G2 phases)
C
Anaphase
D
M phase (mitosis and cytokinesis)
Verified step by step guidance1
Understand the overall structure of the eukaryotic cell cycle, which consists of Interphase and M phase. Interphase includes G1, S, and G2 phases, while M phase includes mitosis and cytokinesis.
Recall that Interphase is the period when the cell grows, duplicates its DNA, and prepares for mitosis, whereas M phase is the period of actual cell division.
Recognize that cytokinesis is the final step of M phase, where the cytoplasm divides to form two daughter cells, and anaphase is a stage within mitosis where sister chromatids separate.
Compare the durations of these phases: Interphase generally takes much longer because the cell needs time to grow and replicate DNA accurately before division.
Conclude that among the options given, Interphase (G1, S, and G2 phases) is the longest part of the cell cycle in a typical proliferating eukaryotic cell.
