It occurs in the first stage.
The chromosomes in a cell's nucleus are only visible during the part of the cell cycle known as prophase. Prophase is the stage of mitosis in which chromatin condensation occurs.
Prophase I of Meiosis.
The specific process that occurs in the cell cycle can vary depending on the stage. In general, DNA replication occurs during the S phase, chromosome segregation happens during the mitotic phase, and cell division occurs during cytokinesis.
The Nuclear membrane dissolves during prophase
The nucleolus begins to fade from view during prophase.

DNA condenses into chromosomes during the prophase stage of the cell cycle.
Crossing over occurs during the prophase I stage of meiosis, not during mitosis.

The nucleolus begins to fade from view during prophase.
The spindle is formed during the prophase stage of mitosis or meiosis. In prophase, microtubules organize into a structure called the spindle apparatus, which helps separate the chromosomes during cell division.
Chromosomes become visible during the prophase stage of the cell cycle, when they condense and can be seen under a microscope as distinct structures. This marks the beginning of cell division.
DNA condenses into chromosomes during the prophase stage of the cell cycle.
Mitosis (prophase, metaphase, anaphase, telophase) occurs during the M phase. This is the part where the chromosomes migrate to either end of the cell and the cell begins to split
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.
