Multiple Choice
In the context of the overview of the cell cycle, what best describes interphase?
A
A checkpoint phase after mitosis in which the cell permanently exits the cell cycle and cannot re-enter (G0)
B
The period when the cell grows, replicates its DNA, and prepares for mitosis, including the G1, S, and G2 phases
C
The process of cytoplasmic division that produces two daughter cells (cytokinesis)
D
The stage when sister chromatids separate and move to opposite poles of the cell (anaphase)
Verified step by step guidance1
Understand that the cell cycle consists of several phases, including interphase and mitotic phase (M phase).
Recognize that interphase is the phase where the cell is metabolically active and preparing for cell division, rather than the phase where division occurs.
Recall that interphase is subdivided into three stages: G1 (cell growth), S (DNA replication), and G2 (preparation for mitosis).
Note that the other options describe different parts of the cell cycle: G0 is a resting phase outside the cycle, cytokinesis is the division of the cytoplasm, and anaphase is a stage within mitosis.
Conclude that the best description of interphase is the period when the cell grows, replicates its DNA, and prepares for mitosis, encompassing the G1, S, and G2 phases.
