Dividing animal cells become nearly rounded in

Options

A. Interphase
B. Early prophase
C. Late prophase
D. Metaphase

Answer

To answer the question "Dividing animal cells become nearly rounded in," we need to analyze the options provided and understand the cell cycle, particularly the stages of mitosis.

### Step-by-Step Solution:

1. **Understanding the Question**:
- The question asks at which stage of cell division animal cells become nearly rounded. This indicates a change in the shape of the cell as it prepares for division.

2. **Identifying the Stages of Mitosis**:
- The stages of mitosis include Interphase, Prophase (which has early and late phases), Metaphase, Anaphase, and Telophase. We need to focus on the early stages of mitosis to find the correct answer.

3. **Reviewing the Options**:
- **Option A: Interphase** - During interphase, the cell is not dividing and maintains its typical shape.
- **Option B: Early Prophase** - This is the stage where the chromatin condenses into visible chromosomes, and the cell begins to change shape.
- **Option C: Late Prophase** - The cell is still undergoing changes, but the rounding effect is already initiated in early prophase.
- **Option D: Metaphase** - The chromosomes are aligned at the cell's equatorial plane, but the rounding effect has already occurred.

4. **Determining the Correct Answer**:
- The rounding of the cell is a characteristic feature that occurs just before mitosis begins, specifically during the early prophase. Therefore, the correct answer is **Option B: Early Prophase**.

### Final Answer:
The correct answer is **B: Early Prophase**.
