Multiple Choice
During what phase of the cell cycle is DNA replicated?
A
G1 phase of interphase
B
G2 phase of interphase
C
S phase of interphase
D
M phase (mitosis)
Verified step by step guidance1
Understand the phases of the cell cycle: G1 phase (cell growth), S phase (DNA synthesis), G2 phase (preparation for mitosis), and M phase (mitosis, cell division).
Recall that DNA replication is the process of copying the cell's DNA to ensure each daughter cell receives an identical set of chromosomes.
Identify which phase is specifically dedicated to DNA synthesis; this is the S phase of interphase.
Note that G1 and G2 phases involve cell growth and preparation, but not DNA replication itself.
Recognize that M phase is when the cell divides, so DNA replication must occur before this phase, during the S phase.
