The Nuclear membrane dissolves during prophase
The nuclear membrane reforms and chromosomes disappear during the telophase phase of mitosis. In this phase, the separated sister chromatids reach the opposite poles of the cell, and the nuclear envelope begins to reassemble around each set of chromosomes. Subsequently, the chromosomes decondense back into chromatin, preparing for the next cell cycle.
In the telo phase
During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.
The phase where DNA is spread out as chromatin and the nuclear membrane is visible is the interphase. This is the period when the cell is not actively dividing, but preparing for division by duplicating its DNA and organelles.
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.
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.
In the telo phase
Prophase
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.
During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.
Nuclear division
The phase where DNA is spread out as chromatin and the nuclear membrane is visible is the interphase. This is the period when the cell is not actively dividing, but preparing for division by duplicating its DNA and organelles.
"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!!!
