Webb16 sep. 2024 · 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. What happens in prophase simple? WebbMitosis. Mitosis is part of the cycle of cell division. [1] The chromosomes of a cell are copied to make two identical sets of chromosomes, [2] and the cell nucleus divides into two identical nuclei.
