when does dna replication occur?
prophase
metaphase
telophase
g₁ phase
s phase

Explanation:

DNA replication occurs during the S (synthesis) phase of the cell cycle. In this phase, the cell duplicates its DNA to ensure that each daughter cell will have a complete set of genetic material after cell division. Prophase, metaphase, and telophase are stages of mitosis (cell division) where DNA is already replicated (in S phase before mitosis). The G₁ phase is a growth phase before DNA replication (S phase).

Answer:

S phase
