Guida verificata passo dopo passo1
Understand that the cell cycle consists of several stages: G1 phase, S phase, G2 phase (all part of interphase), and M phase (mitosis).
Recall that DNA replication is the process by which a cell duplicates its DNA to ensure each daughter cell receives an identical set of chromosomes.
Identify that DNA replication must occur before mitosis so that the chromosomes can be properly divided between the two new cells.
Recognize that the S phase (Synthesis phase) of interphase is specifically dedicated to DNA replication, where the entire genome is duplicated.
Conclude that DNA replication occurs during the S phase of interphase, not during G1, G2, or M phases.
