Frequent question: Does DNA replication happen in mitosis or meiosis?

Does DNA replication occur in mitosis or meiosis?

In which stage of meiosis does DNA replication occur?

DNA replication for a cell occurs during Synthesis Phase of meiosis. This phase is one of three during the Interphase stage of meiosis.
