In which phase, the synthesis of new DNA molecules takes place?

Explanation

To answer the question "In which phase does the synthesis of new DNA molecules take place?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**: The cell cycle consists of several phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). Each phase has specific functions.

2. **Identifying the S Phase**: The S phase is specifically known as the Synthesis phase. This is the phase where DNA replication occurs.
