Verified step by step guidance1
Understand that the cell cycle consists of several phases: G1 (first gap), S (synthesis), G2 (second gap), and M (mitosis).
Recall that DNA replication, which involves copying chromosomes, occurs during the S phase of interphase to prepare for cell division.
Recognize that metaphase, anaphase, and prophase are stages within mitosis, where chromosomes are already replicated and being separated or organized.
Identify that the S phase is specifically dedicated to synthesizing new DNA, ensuring each daughter cell receives an identical set of chromosomes.
Conclude that chromosomes are replicated during the S phase of interphase, prior to the mitotic phases such as prophase, metaphase, and anaphase.
