Prophase i stages
WebbMITOSIS The stages of Mitosis are: Prophase – The chromosomes shorten and thicken. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids break apart at the centromere and move to opposite poles. Telophase – Two nuclei formed after nuclear envelopes reform around each group of chromosomes.

The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G 1 and G 2, the so-called gap phases — are less dramatic but equally ...

Webb11 apr. 2024 · Meiosis is the process of cell division that produces gametes (sex cells) in sexually reproducing organisms. It involves two rounds of cell division, known as meiosis I and meiosis II, which result in the production of four haploid daughter cells from a diploid parent cell.
