DNA Replication
Multiple Choice
Chromosomes are duplicated during which portion of the cell cycle?
A
G1 phase of interphase
B
M phase (mitosis)
C
S phase of interphase
D
G2 phase of interphase
Verified step by step guidance1
Understand the phases of the cell cycle: G1 phase, S phase, G2 phase (all part of interphase), and M phase (mitosis).
Recall that the cell cycle is divided into interphase (cell growth and preparation) and mitosis (cell division).
Identify that chromosome duplication means DNA replication, which is necessary before cell division.
Know that DNA replication occurs specifically during the S phase (Synthesis phase) of interphase.
Conclude that chromosomes are duplicated during the S phase of interphase, not during G1, G2, or M phases.
