Kinetochore is present in :-

Options

A. Mitochondria
B. Sphaerosome
C. Chromosome
D. Flagella

Answer

**Step-by-Step Solution:**

1. **Understand the term "Kinetochore":**
- Kinetochore is a protein structure that forms on the chromatids during cell division. It plays a crucial role in the movement of chromosomes.

2. **Identify the function of Kinetochore:**
- The primary function of the kinetochore is to serve as the attachment point for spindle fibers during cell division. These spindle fibers are responsible for pulling the sister chromatids apart to ensure that each daughter cell receives an identical set of chromosomes.

3. **Analyze the options provided:**
- **Option A: Mitochondria** - Mitochondria are organelles involved in energy production and do not contain kinetochores.
- **Option B: Sepharosome** - This is not a standard biological term associated with kinetochores, and thus can be ruled out.
- **Option C: Chromosome** - Chromosomes are structures that contain genetic material, and kinetochores are specifically located at the centromere of chromosomes.
- **Option D: Flagella** - Flagella are tail-like structures that aid in cell movement and do not have kinetochores.

4. **Select the correct answer:**
- Based on the analysis, the correct answer is **Option C: Chromosome**, as kinetochores are present on chromosomes where they facilitate the attachment of spindle fibers during cell division.

**Final Answer: Kinetochore is present in: C) Chromosome.**
