Which of the cilia protein is analogous to myosin of muscles :-

Options

A. Tubulin
B. Dynien
C. Flagellin
D. None of the above

Answer

To answer the question "Which of the cilia protein is analogous to myosin of muscles?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a cilia protein that has a similar function to myosin, which is a well-known motor protein involved in muscle contraction.

2. **Identify Myosin's Function**: Myosin is a motor protein that interacts with actin filaments to facilitate muscle contraction. It hydrolyzes ATP to generate force and movement.

3. **Examine the Options**: The options provided are:
- Tubulin
- Dynein
- Flagellin
- None of the above

4. **Analyze Each Option**:
- **Tubulin**: This is a protein that forms microtubules, which are structural components of the cell, but it does not function as a motor protein.
- **Dynein**: This is a motor protein that moves along microtubules and is responsible for the beating of cilia and flagella, similar to how myosin functions in muscles.
- **Flagellin**: This is a protein that makes up the structure of flagella, not a motor protein.
- **None of the above**: This option would imply that none of the listed proteins are analogous to myosin.

5. **Determine the Correct Answer**: Since dynein is a motor protein that plays a similar role in cilia and flagella as myosin does in muscle contraction, dynein is the correct answer.

### Final Answer:
The cilia protein that is analogous to myosin of muscles is **dynein**.
