metaphase
The nuclear membrane begins to fade during the prophase stage of mitosis, which is the phase in the cell cycle when the chromatin condenses into chromosomes and the nuclear envelope breaks down. This allows the chromosomes to be better organized for separation during cell division.
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.
The phase of mitosis that the nucleus forms is the prophase phase.
"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.
Prophase
The nuclear membrane begins to fade during the prophase stage of mitosis, which is the phase in the cell cycle when the chromatin condenses into chromosomes and the nuclear envelope breaks down. This allows the chromosomes to be better organized for separation during cell division.
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 nuclear membrane begins to fade from view during prophase, which is the first stage of mitosis. As the cell prepares for division, the nuclear membrane breaks down to allow the chromosomes to move freely within the cell.
When the M phase, or mitosis, begins during the cell cycle, it starts with prophase. Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, the nuclear membrane breaks down, and the mitotic spindle begins to form.
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.
The phase of mitosis that the nucleus forms is the prophase phase.

Phase 1- Mitosis begins. Chromosomes condense from long strands into rodlike structures. Phase 2- The nuclear membrane is dissolved. Paired chromatids align at the cell's equator. Phase 3- The paired chromatids separate and move to opposite sides of the cell. Phase 4- A nuclear membrane forms around each set of chromosomes, and the chromosomes decondense. Mitosis is complete.
The nuclear membrane reforms around the nucleus during Telophase, the last phase of mitosis.
Nuclear envelope begins to reappear in the telophase stage of mitosis.
