The cell cycle of somatic cell usually consists of

Options

A. long interphase followed by short mitotic phase
B. short interphase and long mitotic phase
C. long interphase and long mitotic phase
D. short interphase

Answer

To answer the question regarding the cell cycle of somatic cells, we can break down the solution into several steps:

### Step-by-Step Solution:

1. **Understanding Somatic Cells**:
- Somatic cells are the body cells in an organism, excluding germ cells (sperm and egg). They make up most of the tissues and organs in the body.

2. **Identifying the Cell Cycle Phases**:
- The cell cycle consists of two main phases: Interphase and Mitotic phase (M phase).
- Interphase is the phase where the cell prepares for division, and it includes growth and DNA replication.
- The Mitotic phase is where the actual division of the cell occurs.

3. **Duration of Phases**:
- In somatic cells, the Interphase is typically longer than the Mitotic phase. This is because cells spend most of their time in Interphase, preparing for division.
- The Mitotic phase, while crucial, is relatively short compared to Interphase.

4. **Evaluating the Options**:
- Option A: Long interphase followed by short mitotic phase – This aligns with the understanding that Interphase is longer.
- Option B: Short interphase and long mitotic phase – This is incorrect based on the previous analysis.
- Option C: Long interphase and long mitotic phase – This is incorrect as the Mitotic phase is shorter.
- Option D: Short interphase – This is incomplete as it does not mention the Mitotic phase.

5. **Conclusion**:
- Based on the analysis, the correct answer is **Option A: long interphase followed by short mitotic phase**.

### Final Answer:
The cell cycle of somatic cells usually consists of **long interphase followed by short mitotic phase** (Option A).
