Microtubule is involved in the

Options

A. Muscle contraction
B. Membrane architecture
C. cell divison
D. DNA recognition

Answer

**Step-by-Step Solution:**

1. **Understand Microtubules**: Microtubules are one of the three main components of the cytoskeleton in eukaryotic cells. They are tubular structures made of protein subunits called tubulin.

2. **Role in Cytoskeleton**: Microtubules play a crucial role in maintaining the shape and structure of the cell. They are fibrous and provide structural support.

3. **Types of Cytoskeletal Structures**: The cytoskeleton consists of three types of structures:
- Microtubules
- Microfilaments
- Intermediate filaments

4. **Functions of Microtubules**: Microtubules have several important functions, including:
- Forming the spindle apparatus during cell division (mitosis and meiosis).
- Being a structural component of centrioles and basal bodies.
- Making up the structure of cilia and flagella, which are involved in cell movement.

5. **Analyzing the Options**: The question likely provides multiple-choice answers regarding the involvement of microtubules.
- Muscle contraction: Incorrect, as microtubules are not directly involved in this process.
- Membrane architecture: Incorrect, as this is not a primary function of microtubules.
- Cell division: Correct, as microtubules are essential for forming the spindle apparatus during cell division.
- DNA recombination: Incorrect, as this process does not involve microtubules.

6. **Conclusion**: Based on the analysis, the correct answer to the question about what microtubules are involved in is **cell division**.
