Mitosis



It consists of two main stages.
Karyokinesis : This is the main part of cell division, which is the division of the nucleus. It is further divided into four stages.
  • Prophase : The nucleus of the cell breaks apart. The individual chromsomes are visible as the chromatids condense.
  • Metaphase : The centromeres of the chromosomes align along what is called as the metaphase plate.
  • Anaphase : The chromatids separate and get pulled apart by the mitotic spindles forming two arrangements.
  • Telophase : The chromatids condense and form the two daughter nuclei of the cell.
Cytokinesis : This stage happens simultaneously with Telophase. It is the final stage where a cleavage is created in the cytoplasm and the cell separates into two daughter cells. The two daughter nuclei pass into the daughter cells.
