The centrosomes.
chromosomes
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.
During this phase of mitosis, known as prophase, the centrioles move to opposite poles of the cell. As the centrioles migrate, they begin to form the mitotic spindle, the structure that will help separate the chromosomes during cell division.
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.
During prophase of mitosis, chromosomes condense and become shorter. As mitosis progresses, the condensed chromosomes move to the center of the cell and eventually separate during anaphase.
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.
Chromosomes
something very important
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.
In prophase, a cell's nucleus contains the full set of chromosomes, which for humans is 46 chromosomes (23 pairs). At this stage, the chromosomes condense and become visible under a microscope as they prepare for cell division.
Chromosomes condense and form during the prophase stage of mitosis. This is when the chromatin fibers in the nucleus tighten and become visible as distinct structures through a microscope.
