Webb10 mars 2024 · Prometaphase is the stage of mitosis in between prophase and metaphase. The major event is the disintegration of the nuclear envelope, forming many membrane vesicles. Because the nuclear envelope disintegrates, it seems to “ disappear “. The same thing happens to the nucleolus; it disassembles. WebbWhich phase of mitosis is the opposite of prophase? telophase In this way a complete set of chromosomes migrates toward each centriole. In the last phase—telophase—the cell divides. The changes now taking place are the reverse of those that occurred during prophase: the chromosomes uncoil, new membranes form around the nuclei, and the …

WebbDuring prophase, the chromosomes coil up, and sister chromatids become visible under a microscope. The nuclear membrane surrounding the chromosomes also disappears. In metaphase, the sister chromatids align in the center of the cell, attached to spindle fibers. During anaphase, the sister chromatids separate and move to opposite poles of the cell.
