Verified step by step guidance1
Understand the cell cycle: The cell cycle consists of several phases that a cell goes through to divide and replicate. These phases are G1, S, G2, and M.
Identify the purpose of each phase: G1 phase is the first gap phase where the cell grows and prepares for DNA replication. S phase is the synthesis phase where DNA replication occurs. G2 phase is the second gap phase where the cell prepares for mitosis. M phase is the mitosis phase where cell division occurs.
Focus on DNA replication: DNA replication is a crucial process where the cell duplicates its chromosomes to ensure each daughter cell receives a complete set of genetic information.
Determine the phase for DNA replication: Since DNA replication involves synthesizing new DNA strands, it occurs during the S phase of the cell cycle.
Conclude the answer: Based on the understanding of the cell cycle phases, the chromosomes are replicated during the S phase.
