The centrosomes move away from each other and the nuclear envelope breaks up during which phase of mitosis?
The movement of centrosomes away from each other and the breakdown of the nuclear envelope are characteristic events that occur during the prophase phase of mitosis. During prophase, the genetic material (chromatin) inside the nucleus condenses and forms distinct chromosomes. The centrosomes, which contain the centrioles, migrate to opposite poles of the cell, causing the microtubules known as spindle fibers to extend and attach to the chromosomes. At the same time, the nuclear envelope disassembles, allowing the spindle fibers to interact with the chromosomes. This dynamic rearrangement of cellular components prepares the cell for the subsequent stages of mitosis.
