Webb17 dec. 2016 · Prophase is the starting stage of cell division in eukaryotes. Prophase, in both mitosis and meiosis, is recognized by the condensing of chromosomes and separation of the centrioles in the centrosome. This organelle controls the microtubules in the cell, and each centriole is one half of the organelle. WebbSince cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase. Meiosis I Before entering meiosis I, a cell must first go through interphase.

WebbS is the period of DNA synthesis, where cells replicate their chromosomes. G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs. M is the actual period of cell division, consisting of prophase, metaphase, anaphase ... WebbMitosis is divided into four stages (PMAT) listed below. Prophase → Metaphase → Anaphase → Telophase. Cytokinesis, the process of cell division, occurs during the last stage of mitosis (telophase). Some cells do not go though mitosis. In this case, these cells move from G 1 of the cell cycle into a resting phase known as G 0.

WebbList two reasons. Meiosis 1: The chromosomes remain in a replicated state. The number of chromosomes are reduced in half. Meiosis 2: The two chromatids separate. The number of chromosomes remain the same. Ans. Meiosis I is preceded by DNA replication, whereas meiosis II is not preceded by replication.
