During mitosis, the nuclear envelope dissolves during a phase called prophase. Prophase is the first stage of mitosis, during which the chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down, allowing the spindle apparatus to access the chromosomes. The complete breakdown of the nuclear envelope is critical for the subsequent stages of mitosis, allowing for the proper alignment and separation of chromosomes.
during mitosis when does the nuclear envelope dissolve?
