alleryDNA replication in the cell cycle happens in
AS phase (Synthesis), between G1 and G2
BG1 phase, right after the previous division
CM phase, while chromosomes line up
DG0 phase, while the cell is resting
Answer & Solution
Correct answer: A. S phase (Synthesis), between G1 and G2
DNA replication occurs in S phase of interphase, between G1 and G2. After S, each chromosome has two sister chromatids.
G1 and G2 are growth phases
M phase is the actual division
G0 is a resting exit from the cycle.
