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.
What else can I help you with?
During what phase of mitosis is the DNA duplicated?
During the S phase of the cell cycle, which occurs before mitosis, the DNA is duplicated.
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.
During which phase of mitosis is the DNA duplicated?
During the S phase of the cell cycle, which occurs before mitosis, the DNA is duplicated through the process of DNA replication.
In what phase of mitosis does DNA replication occur?
DNA replication occurs during the S phase of the cell cycle, which is before mitosis begins.
When does DNA replicate during mitosis?
DNA replicates during the S phase of the cell cycle, which occurs before mitosis.
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.
During what phase of mitosis is the DNA duplicated?
During the S phase of the cell cycle, which occurs before mitosis, the DNA is duplicated.
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.
During what phase of mitosis does the spindle disperse?
The answer is telophase.
During Mitosis at which phase do the cells divide?
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 which phase of mitosis is the DNA duplicated?
During the S phase of the cell cycle, which occurs before mitosis, the DNA is duplicated through the process of DNA replication.
