Want this question answered?
The nuclear membrane reforms around the nucleus during Telophase, the last phase of mitosis.
This is actually a bio question, but during the final phase, telophase.
During mitosis, it is when the cell is in telophase.
The Nuclear membrane dissolves during prophase
During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.
"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!!!
Telophase, as that is when the nuclear envelope reforms.
prometaphase
In mitosis the nuclear envelope begins to break in prophase. In meiosis the nuclear envelope begins to break in prophase 1.
Prophase
In the telo phase
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.
