A cell cycle consists of :-

Options

A. Mitosis and meiosis
B. `G_(1)`, S, `G_(2)` phase
C. Prophase, Metaphase, Anaphase and telophase
D. Interphase and mitosis

Answer

**Step-by-Step Solution:**

1. **Understanding the Cell Cycle**: The cell cycle is a series of phases that a cell goes through to divide and replicate. It consists of two main parts: interphase and mitosis.

2. **Identifying Interphase**: Interphase is the preparative phase where the cell prepares for division. It is divided into three sub-phases:
- **G1 Phase**: The first gap phase where the cell grows and synthesizes proteins.
- **S Phase**: The synthesis phase where DNA is replicated.
- **G2 Phase**: The second gap phase where the cell continues to grow and prepares for mitosis.

3. **Understanding Mitosis**: Mitosis is the actual process of cell division, which is further divided into several stages:
- **Prophase**: Chromatin condenses into chromosomes, and the nuclear envelope begins to break down.
- **Metaphase**: Chromosomes align at the cell's equatorial plane.
- **Anaphase**: Sister chromatids are pulled apart to opposite poles of the cell.
- **Telophase**: The chromosomes de-condense, and the nuclear envelope re-forms around each set of chromosomes.

4. **Conclusion**: The complete cell cycle consists of both interphase and mitosis. Therefore, the correct answer is that the cell cycle consists of interphase and mitosis.

**Final Answer**: The cell cycle consists of interphase and mitosis.
