During which phase of mitotic cell division the 'DNA replication' occurs?Group of answer choicesTelophaseAnaphaseMetaphaseInterphase

Break Down the Problem

1. Identify the phases of mitotic cell division.
2. Determine when DNA replication occurs in the cell cycle.

Relevant Concepts

• The cell cycle consists of several phases: Interphase, Mitosis (which is divided into prophase, metaphase, anaphase, and telophase).
• DNA replication is a crucial process that doubles the genetic material before cell division.

Analysis and Detail

1. Interphase: This is the phase where the cell prepares for division, including the synthesis of DNA.

   • G1 phase: Cell grows, and organelles are replicated.
   • S phase (Synthesis): Here, DNA replication occurs, resulting in two copies of each chromosome.
   • G2 phase: The cell continues to grow and prepares for mitosis.

2. Mitosis: This phase does not involve DNA replication. It consists of:

   • Prophase
   • Metaphase
   • Anaphase
   • Telophase

Verify and Summarize

DNA replication specifically occurs during the S phase, which is a part of Interphase. The other phases (Prophase, Metaphase, Anaphase, and Telophase) are all part of mitotic division and do not involve DNA replication.

Final Answer

The DNA replication occurs during Interphase.
