In eukaryotic cells, when is the DNA in chromosomes replicated during the cell cycle?
A
During mitosis (M phase)
B
During S phase of interphase
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 (first gap), S phase (synthesis), G2 phase (second gap), 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 occurs specifically during the S phase, where the cell synthesizes a complete copy of its DNA.
Note that during G1 and G2 phases, the cell is preparing for DNA replication and mitosis, respectively, but actual DNA synthesis does not occur.
Recognize that mitosis (M phase) is when the cell divides, not when DNA is replicated.
