Which of the following dyes is best suited for staining chromosomes

Options

A. Basic Fuchsin
B. Safranin
C. Methylene blue
D. Carmine

Explanation

To determine which dye is best suited for staining chromosomes, we will analyze each of the given options:

1. **Basic Fuchsin**:
- This is a green crystalline dye primarily used for staining tissue sections. It is not specifically used for staining chromosomes.

2. **Saffronin**:
- Saffronin is used to stain gram-negative bacteria. It is not suitable for staining chromosomes.

3. **Methylene Blue**:
- Methylene blue is a blue dye that is commonly used to examine DNA or RNA under a microscope. While it can stain nucleic acids, it is not the best choice specifically for chromosomes.

4. **Carmine**:
- Carmine is a red dye that is specifically used for staining chromosomes. It is well-known for its effectiveness in highlighting chromosomal structures during microscopy.

After analyzing all the options, we can conclude that the best dye for staining chromosomes is **Carmine** (Option D).

### Final Answer:
The best suited dye for staining chromosomes is **Carmine** (Option D).
