Which of the following fuctions like mitotic poison?

Options

A. Colchicine
B. Monosodium Glutamate
C. Kinetin
D. 2,4 - D

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks which of the given options functions like a mitotic poison. A mitotic poison is a substance that inhibits or blocks the process of mitosis (cell division).

2. **Identifying the Options**: The options provided are:
- A) Colchicin
- B) Monosodium glutamate
- C) Kinetin
- D) 2,4-D (2,4-Dichlorophenoxyacetic acid)

3. **Analyzing Each Option**:
- **Colchicin**: This is known to inhibit mitosis by preventing microtubule polymerization, which is essential for spindle fiber formation during cell division. Thus, it acts as a mitotic poison.
- **Monosodium Glutamate (MSG)**: This is primarily used as a flavor enhancer in food and does not have any role in inhibiting mitosis. Therefore, it is not a mitotic poison.
- **Kinetin**: This is a type of cytokinin, which is a plant hormone that promotes cell division. It does not inhibit mitosis, making it incorrect as a mitotic poison.
- **2,4-D**: This is a synthetic herbicide used to control weeds and does not function as a mitotic poison.

4. **Conclusion**: Among the options, only **Colchicin** functions like a mitotic poison as it inhibits the process of mitosis.

5. **Final Answer**: The correct answer is **A) Colchicin**.
