Tubulin protein is synthesized in which phase of cell cycle?

Options

A. Prophase
B. Metaphase
C. Interphase
D. Telophase

Answer

To determine the phase of the cell cycle during which tubulin protein is synthesized, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Cell Cycle**: The cell cycle consists of two main phases: Interphase and M phase (mitotic phase). Interphase is further divided into G1, S, and G2 phases, while M phase includes prophase, metaphase, anaphase, and telophase.

2. **Identify the Role of Tubulin**: Tubulin is a protein that forms microtubules, which are essential for various cellular functions, including the formation of the mitotic spindle during cell division.

3. **Determine When Tubulin is Needed**: While tubulin is crucial during the M phase for the assembly of chromosomes on the metaphase plate, it is synthesized during the interphase. This is because the cell needs to prepare sufficient amounts of tubulin before it enters mitosis.

4. **Conclude the Correct Phase**: Since tubulin protein is synthesized in preparation for cell division, the correct answer to the question is **interphase**.

### Final Answer:
**Tubulin protein is synthesized during the interphase of the cell cycle.**
