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)
