Meiosis involves two divisions
WebThe G2 (second growth or gap) part prepares the cell for division. it includes replication of the mitochondria and alternative organelles, synthesis of microtubules and supermolecule that may structure the mitotic spindle fibers, and body condensation. The M (mitotic) part includes events related to partitioning chromosomes between 2 girl cells ... WebMeiosis I. Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase, which is also called the first gap phase, is the first phase of the interphase and is focused on cell growth. The S phase is the second phase of interphase, during which the DNA of ...
