WebbMitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself.

WebbThe cell cycle is made up of two main stages: interphase and mitosis. During interphase, cells are duplicating their material and synthesising proteins to prepare to divide. Interphase encompasses 3 phases: G1, S and G2. During S phase, DNA is replicated. Mitosis encompasses prophase, prometaphase, metaphase, anaphase telophase. Webb23 apr. 2024 · Mitosis has five different stages: interphase, prophase, metaphase, anaphase and telophase. The process of cell division is only complete after cytokinesis, which takes place during anaphase and telophase. Each stage of mitosis is necessary for cell replication and division.

Prophase is the first stage of mitosis. During this stage, the nucleus of the cell begins to disappear and the chromatin, or genetic material, condenses into visible chromosomes.

WebbProphase 1. The initial step of Meiosis 1 is Prophase 1, which takes place in a similar manner to Prophase in Mitosis. The genes get dense and move towards the central portion of the cell. The nuclear membrane disintegrates, and the microtubules on either side of the cell. Further, they attach the kinetochores of each chromosome to the centrioles.
