Use this diagram to match the cell cycle phase with the best answer G2 Checkpoint DNA duplication (approx. 8 hours) S Cell growth (approx.4 hours) G2 PROPHASE M (approx.1-2 hours). METAPHASE ANAPHASE TELOPHASE < Item 12 G1 CYTOKINESIS G1 Checkpoint Go Cell growth (approx: 10 hours) (1 point) Mitosis Cell Growth Interphase DNA Duplication LESSON FEEDBACK G: takes about 10 hours where cell division occurs S takes about 8 hours G+S+G=

Answer 1

Based on the information provided, here’s a summary of the cell cycle phases and their corresponding descriptions:

1. **G1 Phase (Gap 1)**:
- Description: Cell growth
- Duration: Approximately 10 hours
- Associated term: Cell Growth

2. **S Phase (Synthesis)**:
- Description: DNA duplication
- Duration: Approximately 8 hours
- Associated term: DNA Duplication

3. **G2 Phase (Gap 2)**:
- Description: Preparing for mitosis/cell growth
- Duration: Not specifically given in your text, but typically longer than the M phase.
- Associated terms: Checkpoint and Interphase

4. **M Phase (Mitosis)**:
- Subphases: Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
- Duration: Approximately 1-2 hours
- Associated term: Mitosis

To match the phases with the best answers:

- **G2 Checkpoint**: Preparation for mitosis
- **DNA Duplication (S Phase)**: Synthesis
- **G1 Checkpoint**: Cell growth
- **Mitosis**: Contains prophase, metaphase, anaphase, telophase, and cytokinesis

You also mentioned the durations:

- G1 (10 hours) + S (8 hours) + G2 (typically a shorter duration) generally adds to the interphase duration, while M (1-2 hours) includes all stages of mitosis.

In summary, the matches would be:

- G1 Phase → Cell Growth
- S Phase → DNA Duplication
- G2 Phase → Checkpoint (and part of Interphase)
- M Phase → Mitosis (including prophase, metaphase, anaphase, telophase, cytokinesis)
