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.
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.
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 nuclear membrane reforms around the chromosomes during telophase of mitosis. Telophase marks the end of nuclear division and the beginning of cytoplasmic division.
Prophase
In the telo phase
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.
The phase in mitosis where the nuclear membrane disappears is called prometaphase. During prometaphase, the nuclear envelope breaks down, allowing the mitotic spindle to interact with the chromosomes.
telophase
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.
