Here's what happens: 1  At first the cells have the same number of chromosomes as mitosis. DNA replication occurs, giving a total of 46 chromosomes (or 23 chromosome pairs) and 92 chromatids (or 46 chromatid pairs). 2  Meiosis I: In meiosis I, the homologous chromosomes separate.
DNA replicatioin occurs before mitosis. It happens during INTERPHASE. DNA has to replicate because DNA contains the genetic blueprint for the cell. It tells the cell how to function and how it is to form. Also, the daughter cells must each have their own set of equal DNA. Shortly before cell division (Mitosis).
