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: G1 phase is the first gap phase where the cell grows and prepares for DNA replication. S phase is where DNA replication occurs, resulting in the duplication of chromosomes. G2 phase is the second gap phase where the cell continues to grow and prepares for mitosis. M phase is where mitosis occurs, leading to cell division.
Focus on the S phase: During the S phase, each chromosome is duplicated. This is crucial for ensuring that each daughter cell receives an identical set of chromosomes during cell division.
Recognize the importance of chromosome duplication: Chromosome duplication is essential for genetic consistency across cell generations, allowing for proper cell function and organism development.
Conclude with the correct phase: Based on the understanding of the cell cycle, the phase during which chromosomes are duplicated is the S phase.
