In prophase stage, the replicated chromosomes condense and the nuclear envelope disappears. Earlier in prophase, chromatin visible condenses into the chromosomes.
The nuclear membrane disappears during prophase of mitosis. This allows the chromosomes to be condensed and move freely within the cell. At the end of mitosis, during telophase, the nuclear membrane reforms around the separated chromosomes.
The second phase of mitosis is called prophase. During prophase, chromosomes condense and become visible as distinct structures. In addition, the nuclear membrane starts to break down, allowing the chromosomes to move freely within the cell.
"scientist have not discovered WHY it happens"It does not matter if scientists have discovered it or not, but the nuclear membrane disappears during PROPHASEHope this helped!!!
The nuclear membrane reforms around the nucleus during Telophase, the last phase of mitosis.
The phase of mitosis that begins when the nuclear membrane starts to fade is called prometaphase. During prometaphase, the nuclear membrane breaks down, allowing the spindle fibers to attach to the chromosomes.
Prophase
The nuclear membrane fades during the prophase of mitosis or meiosis. This is the stage when the membrane begins to break down and disappear, allowing the chromosomes to become more condensed and accessible for cell division.

The phase where the nucleus and the nuclear membrane disappear is called prometaphase. This is the phase following prophase in mitosis or meiosis when the nuclear envelope breaks down and the chromosomes become more condensed and visible.

telophase
Before the nuclear envelope of a cell breaks down during the mitosis process, the DNA has to be duplicated. After the envelope dissolves, the chromosomes separate, then the cell finally splits.
The nuclear membrane needs to disappear during prophase to facilitate the proper alignment and separation of chromosomes during cell division. By disintegrating, it allows spindle fibers to access the chromosomes, ensuring they can attach to the kinetochores and be effectively pulled apart during later stages of mitosis. This disappearance is crucial for the accurate distribution of genetic material to the daughter cells.
The nuclear membrane forms around each set of chromosomes during telophase, the final stage of mitosis. This process marks the completion of mitosis and leads to the formation of two separate nuclei within the daughter cells.
