Stain for cell division :-

Options

A. Saffranin
B. Aniline blue
C. PAS
D. Acetocarmine

Answer

To answer the question about the stain used for cell division, we will analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Identify the Stains Provided in the Options:**
- The options given are:
1. Safranine
2. Aniline Blue
3. PAS (Periodic Acid-Schiff)
4. Acetocarmine

2. **Evaluate Each Option:**
- **Option 1: Safranine**
- Safranine is primarily used for staining cartilage, mucin, and mast cell granules. It is not specifically used for cell division.
- **Conclusion:** This option is incorrect.

- **Option 2: Aniline Blue**
- Aniline blue is commonly used for staining collagen and is not associated with cell division.
- **Conclusion:** This option is incorrect.

- **Option 3: PAS (Periodic Acid-Schiff)**
- PAS is used to detect polysaccharides and is not specifically a stain for cell division.
- **Conclusion:** This option is incorrect.

- **Option 4: Acetocarmine**
- Acetocarmine is a stain that is specifically used to visualize chromosomes during cell division. It is effective in staining the nuclei and is commonly used in cytological studies.
- **Conclusion:** This option is correct.

3. **Final Answer:**
- The correct stain for cell division from the given options is **Acetocarmine** (Option 4).
