Disappears in prophase and reappears in telophase.
The nuclear envelope reforms and the nucleoli reappear during telophase of mitosis. This phase marks the end of nuclear division as the newly formed daughter nuclei begin to re-establish their nuclear envelopes.
During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.
Nuclear envelope begins to reappear in the telophase stage of mitosis.
The Nuclear membrane dissolves during prophase
In the telo phase
telophase
The nuclear envelope reforms during telophase, which is the final stage of mitosis. In telophase, the nuclear membrane and nucleolus reappear, and the chromosomes begin to decondense back into chromatin.
The nuclear envelope reforms and the nucleoli reappear during telophase of mitosis. This phase marks the end of nuclear division as the newly formed daughter nuclei begin to re-establish their nuclear envelopes.
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.
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!!!
Nuclear envelope begins to reappear in the telophase stage of mitosis.
The Nuclear membrane dissolves during prophase
The nuclear membrane reforms around the nucleus during Telophase, the last phase of mitosis.
prometaphase
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 phase where two new nuclear envelopes form around the two sets of daughter chromosomes is called telophase. In telophase, the nuclear membrane reforms around the chromosomes and the nucleoli reappear. This marks the end of nuclear division in cell mitosis.
