When does DNA replicate in cell cycle of eukaryotes?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Cell Cycle**: The eukaryotic cell cycle consists of several phases that prepare the cell for division. These phases are G1, S, G2, and M.

2. **Phases of the Cell Cycle**:
- **G1 Phase (Gap 1)**: This is the first phase where the cell grows and prepares for DNA replication. The cell accumulates nutrients and energy to support DNA synthesis.
- **S Phase (Synthesis)**: This is the critical phase where DNA replication occurs. Each chromosome is replicated to form two sister chromatids.
- **G2 Phase (Gap 2)**: In this phase, the cell continues to grow and prepares for mitosis. It ensures that all DNA has been replicated correctly and that the cell is ready for division.
