In centriole radial spoke is made of:-

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Centrioles:**
- Centrioles are cylindrical structures found in the cells, primarily involved in cell division and the formation of cilia and flagella.

2. **Identifying Radial Spokes:**
- Within the structure of the centriole, there are components known as radial spokes. These are crucial for the function of centrioles.

3. **Describing the Composition of Radial Spokes:**
- Radial spokes are T-shaped structures that extend from the centriole. Each spoke has two main parts: a head and a tail.

4. **Determining the Material of Radial Spokes:**
- The head and tail of the radial spokes are composed of proteins. This protein composition is essential for the structural integrity and function of the spokes.

5. **Conclusion:**
- Therefore, the radial spokes in the centriole are made up of proteins.

**Final Answer:**
In centriole, the radial spoke is made up of proteins.
