Prophase and prometaphase

WebbIn prometaphase the nuclear envelope breaks down (in many but not all eukaryotes) and the chromosomes attach to the mitotic spindle. Both chromatids of each chromosome attach to the spindle at a specialized … Webb3 mars 2024 · Prometaphase is that phase in mitosis in between prophase and metaphase. It takes place after prophase and preceding metaphase of a dividing eukaryotic cell. However, prometaphase is sometimes considered as part of the prophase, particularly towards the end and prior to metaphase.

WebbProphase is the first stage in mitosis. The nuclear envelope begins to break down and chromosomes condense and are now visible. Spindle fibers start to appear and centrosomes begin to move towards opposite poles. Prometaphase - Chromosomes continue to condense and are more visible. WebbDuring prophase, chromatin (tangled-up DNA) in the nucleus condense into chromosomes (bunched-up DNA). Pairs of centrioles move to opposite sides of the nucleus.
