Web8 jun. 2024 · Meiosis I. Meiosis is preceded by an interphase consisting of three stages. The G 1 phase (also called the first gap phase) initiates this stage and is focused on cell growth. The S phase is next, during which the DNA of the chromosomes is replicated. This replication produces two identical copies, called sister chromatids, that are held ... WebMitosis: Metaphase. When the chromosomes maneuver to the center of the cell, metaphase begins (Fig. 5). The spindle fiber network connects the centromere of the replicated chromosome to the outer part of each cell.
