During which phase of the cell cycle does DNA replication occur?*1 pointInterphaseMetaphaseCytokinesisTelophase

DNA replication occurs during the Interphase of the cell cycle. Here's a step-by-step breakdown:

1. The cell cycle consists of four main phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis).

2. Interphase is a part of the cell cycle where the cell prepares for division. It includes the G1, S, and G2 phases.

3. During the G1 phase, the cell grows and carries out its normal functions. The cell's organelles are also duplicated during this phase.

4. The S phase is where DNA replication occurs. The cell's DNA is copied, ensuring that the two new cells will have identical genetic material.

5. In the G2 phase, the cell continues to grow and prepares for division. It checks the accuracy of DNA replication and repairs any errors.

6. Finally, during the M phase (which includes metaphase, anaphase, telophase, and cytokinesis), the cell divides its copied DNA and cytoplasm to create two new cells.

So, to answer your question, DNA replication occurs during the Interphase, specifically in the S phase.
