During prophase of cell division, the nucleus condenses and the chromatin (DNA and proteins) inside it becomes tightly coiled into chromosomes. The nuclear membrane also breaks down, allowing the chromosomes to become more visible and ready for division.
The breakdown of the nucleus occurs in the prophase stage of mitosis. This is when the nuclear envelope disintegrates, allowing the chromosomes to be released into the cytoplasm for subsequent division.
The phase of mitosis where the nuclear envelope and nucleus disappear is called prophase. During prophase, the chromatin condenses into discrete chromosomes, and the spindle apparatus begins to form, facilitating the movement of chromosomes during cell division.
During prophase of cell division, there are typically 46 cells in humans.
The following process happens in the prophase of mitosis, during which the nuclear envelope will disappear along with the nucleolus. The chromosomes are then ready to be moved to the center to be split.
When the nucleus disappears during prophase, it fragments into vesicles containing membrane and nuclear pore proteins. These vesicles then fuse together to reform the nucleus during telophase.

prophase, metaphase, anaphase, telophase (including cytokinesis)
The phase of mitosis where the nuclear envelope and nucleus disappear is called prophase. During prophase, the chromatin condenses into discrete chromosomes, and the spindle apparatus begins to form, facilitating the movement of chromosomes during cell division.
The presence of two centrioles on one side of the nucleus indicates that the cell is in the prophase stage of mitosis. During prophase, the centrioles move to opposite poles of the cell, forming the mitotic spindle that will help separate the chromosomes during cell division.
During prophase of cell division, there are typically 46 cells in humans.

During mitosis, chromosomes are in their most condensed form during metaphase
Cell division includes a stage known as mitosis (meiosis in gametic cells), which has four phases: prophase, metaphase, anaphase and telophase. Each stage can be differentiated under a microscope by the physical changes visible in the cells nucleus; particularly the chromosomal alignment. In prophase chromatids condense to form chromosomes, the mitotic spindle forms and the nucleur membrane breaks down.
