Today, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
What happens in each phase of mitosis?
Mitosis produces two daughter cells with identical genetic material. … Mitosis has five different stages: interphase, prophase, metaphase, anaphase and telophase. The process of cell division is only complete after cytokinesis, which takes place during anaphase and telophase.
What are the 4 phases or parts of mitosis?
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.
What is the short phase of mitosis?
In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes. In telophase, 2 daughter nuclei form.
How long does each phase of mitosis take?
The time required then for the complete process of mitotic cell division would lie within the following limits: Prophase, 30 to 60 minutes; metaphase, 2 to 10 minutes; anaphase 2 to 3 minutes; telophase 3 to 12 minutes and the reconstruction period from 30 t’o 120 minutes: total 70 to 180 minutes.
Where does mitosis occur in the body?
Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46.
What is the difference between mitosis and meiosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
