WebS phase, or synthesis, is the phase of the cell cycle when DNA packaged into chromosomes is replicated. This event is an essential aspect of the cell cycle because replication allows for each cell created by cell division to have the same genetic make-up. Why does DNA synthesis occur in S phase? Web16 dec. 2024 · DNA replication takes place before mitosis and meiosis. Mitosis involves one round of division, resulting in two diploid cells that are genetically identical to the parent cells. Meiosis involves crossing over and two rounds of division, resulting in four haploid cells that are genetically unique. Why is DNA replication required prior to mitosis?
