Select which of the following phases of mitosis is also called spireme stage?

Options

A. Prophase
B. Metaphase
C. Anaphase
D. Telophase

Answer

To determine which phase of mitosis is referred to as the "spirene stage," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Spirene Stage":**
- The term "spirene" is associated with the early stages of prophase in mitosis.

2. **Identify the Phases of Mitosis:**
- Mitosis consists of several phases:
- Prophase
- Metaphase
- Anaphase
- Telophase

3. **Analyze Each Phase:**
- **Prophase:** This is the stage where chromosomes condense and become visible. The spirene stage occurs during early prophase when chromosomes begin to overlap.
- **Metaphase:** In this stage, chromosomes align at the cell's equator. This is not the spirene stage.
- **Anaphase:** This is when sister chromatids are pulled apart towards opposite poles of the cell. This is also not the spirene stage.
- **Telophase:** This is the final stage of mitosis where the nuclear membrane reforms around the separated chromosomes. This is not the spirene stage either.

4. **Conclusion:**
- Based on the analysis, the spirene stage is synonymous with early prophase. Therefore, the correct answer is the **first option**, which corresponds to early prophase.

### Final Answer:
The phase of mitosis that is also called the spirene stage is **early prophase**.
