The chromosomes coil and become short and visible.
(In animal cells) The centrioles migrate to opposite poles of the cell (the poles are themselves determined by the final position of the chromosomes.)
At the end of prophase, the nucleolus and the nuclear envelope disappear.
During prophase of the cell cycle, the DNA condenses and coils tightly to form visible chromosomes. This process helps to organize and prepare the DNA for cell division.
DNA condenses into chromosomes during the prophase stage of the cell cycle.
DNA condenses into chromosomes during the prophase stage of the cell cycle.
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.
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.
During Prophase
During prophase of the cell cycle, the DNA condenses and coils tightly to form visible chromosomes. This process helps to organize and prepare the DNA for cell division.
The nucleolus begins to fade from view during prophase.

The Nuclear membrane dissolves during prophase
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.

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.
Prophase occurs during the first stage of the cell cycle, which is the mitotic phase. It is characterized by the condensation of chromatin into visible chromosomes, the disintegration of the nuclear envelope, and the formation of the mitotic spindle.
Chromosomes are duplicated during the S phase of the cell cycle, which occurs during interphase. This is when DNA replication takes place to ensure that each daughter cell receives a complete set of chromosomes during cell division.
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.
