Multiple Choice
During the eukaryotic cell cycle, when does DNA replication occur?
A
During S phase of interphase
B
During mitosis (M phase)
C
During G2 phase of interphase
D
During G1 phase of interphase
Verified step by step guidance1
Understand the phases of the eukaryotic cell cycle: G1 phase, S phase, G2 phase (all part of interphase), and M phase (mitosis).
Recall that DNA replication is the process of copying the entire genome to prepare for cell division.
Identify that DNA replication must occur before mitosis so that each daughter cell receives a complete set of chromosomes.
Recognize that the S phase (Synthesis phase) of interphase is specifically dedicated to DNA replication.
Conclude that DNA replication occurs during the S phase of interphase, not during G1, G2, or M phases.
