Verified step by step guidance1
Understand the cell cycle: The cell cycle consists of several phases that a cell goes through to divide and produce new cells. These phases include G1, S, G2, and M.
Identify the purpose of each phase: The G1 phase is where the cell grows and performs its normal functions. The S phase is where DNA replication occurs. The G2 phase is where the cell continues to grow and prepares for mitosis. The M phase is where mitosis and cytokinesis occur.
Focus on DNA replication: The problem asks about the stage where the cell prepares for mitosis by replicating its DNA. DNA replication is a crucial step that ensures each daughter cell receives an identical set of chromosomes.
Determine the correct phase for DNA replication: Based on the understanding of the cell cycle, DNA replication occurs during the S phase (Synthesis phase).
Conclude with the correct phase: Therefore, the cell prepares for mitosis by replicating its DNA during the S phase of the cell cycle.
