Question

in eukaryotic cells, when does dna replication happen?
during mitosis
during meiosis
during interphase
during both mitosis and meiosis

Explanation:

In eukaryotic cells, DNA replication occurs during interphase. Interphase is the phase of the cell cycle where the cell prepares for division. Mitosis and meiosis are phases of cell division where the replicated DNA is distributed to daughter cells. DNA replication does not occur during mitosis or meiosis themselves.

Answer:

During interphase.
