Break Down the Problem

1. Identify the phase of the cell cycle during which DNA replication occurs.
2. Understand the functions of mitosis and meiosis in the cell cycle.

Relevant Concepts

• DNA replication specifically occurs during the S phase of interphase.
• Mitosis is the process of cell division that results in two identical daughter cells, while meiosis is the process that leads to the formation of gametes (sperm and egg cells), resulting in four non-identical cells.

Analysis and Detail

1. Interphase is divided into three phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
2. During the S phase of interphase, the DNA is replicated in preparation for cell division.
3. Mitosis and meiosis do not involve DNA replication during their processes, as that takes place beforehand in the S phase.

Verify and Summarize

• Since DNA replication occurs during interphase and is complete before either mitosis or meiosis takes place, both mitosis and meiosis do not replicate DNA within their respective processes.

Final Answer

DNA replication occurs during interphase, so the correct answer is: neither mitosis nor meiosis.
