Bead like structure found on chromosome are called :–

Options

A. Chromomeres
B. Chromonemata
C. Chromonema
D. Centriole

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the bead-like structures found on chromosomes. We need to identify the correct term that describes these structures.

2. **Analyzing the Options**:
- **Option 1: Chromomeres**: This term refers to the bead-like structures found on eukaryotic chromosomes. They are essentially the serially aligned granules or beads that can be observed during certain stages of cell division.
- **Option 2: Chromonimata**: This term is incorrect as it refers to a coiled filament where genes are located, not bead-like structures.
- **Option 3: Chromonema**: This option is also incorrect. Chromonema refers to the spiral coil of the chromatid, which is not bead-like.
- **Option 4: Centrio**: This term is incorrect as centrioles are involved in cell division but do not refer to bead-like structures on chromosomes.

3. **Identifying the Correct Answer**: Based on the analysis, the correct answer is **Chromomeres** (Option 1). These structures are indeed the bead-like formations found on chromosomes.

4. **Conclusion**: The bead-like structures found on chromosomes are called **Chromomeres**.
