In a typical eukaryotic cell cycle, Gap-I synthesis and Gap-2 are those phases included in the

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Cell Cycle**: The eukaryotic cell cycle consists of several phases: Interphase (which includes G1, S, and G2 phases) and the Mitotic phase (M phase).

2. **Identifying the Phases**:
- **G1 Phase (Gap 1)**: This is the first phase of Interphase where the cell grows, synthesizes proteins, and produces RNA. The cell prepares itself for DNA replication.
- **S Phase (Synthesis)**: In this phase, DNA replication occurs. Each chromosome is duplicated, resulting in two sister chromatids for each chromosome.
- **G2 Phase (Gap 2)**: Following DNA synthesis, the cell enters G2 phase where it continues to grow and prepares for mitosis. This phase involves the synthesis of proteins necessary for cell division.

3. **Evaluating the Options**: The question provides options that include Prophase, Metaphase, Anaphase, and Interphase.
- **Prophase**: This is a stage of mitosis, not part of Interphase.
- **Metaphase**: This is also a stage of mitosis where chromosomes align at the cell's equator.
- **Anaphase**: This is a stage of mitosis where sister chromatids are pulled apart.
- **Interphase**: This is the correct option as it includes G1, S, and G2 phases.

4. **Conclusion**: The phases Gap 1, Synthesis, and Gap 2 are included in the Interphase of the eukaryotic cell cycle.

**Final Answer**: The correct answer is **Interphase**.
