Detailed explanation-1: -Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word “mitosis” means “threads, ” and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
Detailed explanation-2: -During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
Detailed explanation-3: -The large central nucleolus, which occupies about 20% of the nuclear volume, persists throughout the cell cycle. At mitosis, the nucleolus divides and moves to the poles in association with the chromosomes. The structure of the mitotic spindle and its relationship to the nucleolus are unknown.
Detailed explanation-4: -The mitotic phase (M) includes both mitosis and cytokinesis. This is when the nucleus and then the cytoplasm divide.
