Overview of the Cell Cycle
Multiple Choice
Which sequence correctly represents the order of phases in the eukaryotic cell cycle (including interphase and mitosis/cytokinesis)?
A
G1 → G2 → S → M (mitosis) → cytokinesis
B
S → G1 → G2 → M (mitosis) → cytokinesis
C
G1 → M (mitosis) → S → G2 → cytokinesis
D
G1 → S → G2 → M (mitosis) → cytokinesis
Verified step by step guidance1
Step 1: Understand that the eukaryotic cell cycle consists of two major parts: interphase and the mitotic phase. Interphase includes G1, S, and G2 phases, while the mitotic phase includes mitosis (M) and cytokinesis.
Step 2: Recognize the order of events in interphase: the cell first grows and performs normal functions during G1 (Gap 1), then duplicates its DNA during the S (Synthesis) phase, and finally prepares for mitosis during G2 (Gap 2).
Step 3: After interphase, the cell enters the mitotic phase, starting with mitosis (M), where the duplicated chromosomes are separated into two nuclei.
Step 4: Cytokinesis follows mitosis, completing cell division by physically splitting the cytoplasm into two daughter cells.
Step 5: Combine these phases in the correct sequence to represent the full cell cycle: \(G1 \rightarrow S \rightarrow G2 \rightarrow M \rightarrow \text{cytokinesis}\).
