Multiple Choice
During which phase of the cell cycle are chromosomes replicated (DNA synthesis occurs)?
A
G1 phase of interphase
B
M phase (mitosis)
C
G2 phase of interphase
D
S 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 G1 phase is primarily for cell growth and preparation for DNA replication, but DNA synthesis does not occur here.
Recognize that the S phase (Synthesis phase) is the specific period during interphase when DNA replication takes place, resulting in duplicated chromosomes.
Know that the G2 phase is for further growth and preparation for mitosis, but DNA replication is already complete by this phase.
Identify that the M phase is when mitosis occurs, involving chromosome segregation and cell division, not DNA replication.
