Mitosis can be divided into four main stages. These are prophase, metaphase, anaphase and telophase.
During prophase, the chromosomes condense and become shorter and thicker, making them easily seen under a light microscope. The centrioles divide and move to opposite poles of the cell. The spindle develops from the centrioles. Towards the end of prophase, the nuclear membrane and nucleoli disappear.
During metaphase, the chromosomes line up at the equator of the cell and become attached to the spindle fibres at their centromeres. One sister chromatid is attached to a spindle fibre from one pole, whereas the other sister chromatid is attached to a spindle fibre from the opposite pole.
Anaphase is a very rapid stage. The centromere splits, the spindle fibres contract and separate the sister chromatids by pulling them to opposite poles of the cell, centromere first. As they are now separated, they are referred to as chromosomes in their own right.
Telophase begins when two distinct new groups of chromosomes have formed at opposite poles of the cell. The chromosomes uncoil and lengthen and become less visible under a microscope. The nuclear membrane and nucleoli reform. Cytokinesis occurs where the cytoplasm itself divides. In animal cells, this occurs by the constriction of the centre of the parent cell from the outside inwards. In plant cells, a new cell plate forms across the equator of the parent cell from the centre outwards and a new cell wall is laid down. These processes produce two new distinct daughter cells.
During mitosis, a cell divides its nucleus into two identical daughter nuclei. The phases of mitosis include prophase (chromosomes condense), metaphase (chromosomes align at cell's center), anaphase (chromatids separate and move to opposite poles), and telophase (chromosomes de-condense and nuclear envelopes reform). Finally, cytokinesis divides the cell into two daughter cells.

During which main phase of the cell cycle do mitosis abd cytokinesis occur?
Mitosis and cytokinesis occur during the M phase (mitotic phase) of the cell cycle. This phase is characterized by cell division, where the cell replicates its DNA and divides into two daughter cells.
The phase of mitosis in which doubling of the centrioles occurs is?
The phase of mitosis in which doubling of the centrioles occurs is the G1 phase. During this phase, the centrioles replicate to ensure that each daughter cell will receive a complete set of centrioles.
Where is the phase where cell division occurs?
Chromosome separation and the cyto-kinetic movement of Cytoplasmic components including the Cell's Membrane occurs during The M Phase.
Which phase is the DNA replicated in during mitosis?
DNA replication occurs during interphase, specifically in the S phase. Mitosis itself is the phase of cell division where the replicated DNA is separated into two daughter cells.
In what stage do centrioles replicate?
Centrosomes replicate during the S phase of the CELL CYCLE not mitosis. Mitosis is one stage of the cell cycle. Replication does not happen during mitosis(M phase). It happens during the S phase. In fact, the opposite happens chromosomes are consdensed and packaged in preparation for splitting.
What is occurring during mitosis phase?
during which the cell is replicating itself.
What is occurring the mitosis phase?
during which the cell is replicating itself.
What is occurring during the mitosis?
during which the cell is replicating itself.
What phase happens during mitosis?
Prophase.
What is duplicated during the process of mitosis?
DNA duplication occurs during the interphase, specifically the S phase. After replication, the cell then enters the first active phase of mitosis.
During which main phase of the cell cycle do mitosis abd cytokinesis occur?
Mitosis and cytokinesis occur during the M phase (mitotic phase) of the cell cycle. This phase is characterized by cell division, where the cell replicates its DNA and divides into two daughter cells.
What point in mitosis does cytokinesis occur?
Mitosis occurs during the last phase- Telophase.
What phase of the cell cycle does mitosis start?
Mitosis begins during the M phase of the cell cycle, which is also known as the mitotic phase. This phase includes mitosis, where the nucleus divides, and cytokinesis, where the cytoplasm divides, resulting in two daughter cells.
During what phase of mitosis does the spindle disperse?
The answer is telophase.
During Mitosis at which phase do the cells divide?
telophase
In cell cycle where mitosis occurs?
Mitosis occurs during the cell cycle in the M phase. This phase follows the G2 phase and is essential for cell division and reproduction. During mitosis, the cell nucleus divides into two identical daughter nuclei.
The phase of mitosis in which doubling of the centrioles occurs is?
The phase of mitosis in which doubling of the centrioles occurs is the G1 phase. During this phase, the centrioles replicate to ensure that each daughter cell will receive a complete set of centrioles.
