NEET BIOLOGY

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 the completion of mitosis (telophase), two new nuclei form around the separated sets of daughter chromosomes (see Figure 8.29).

Detailed explanation-3: -During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Detailed explanation-4: -Upon mitosis, each daughter cell inherits one pole of the spindle and hence one centrosome consisting of one pair of parental centrioles. This pair splits during early mitosis to seed the formation of the two centrosomes at the opposite poles of the mitotic spindle.

Detailed explanation-5: -Mitosis divides the nucleus into two nuclei, followed by cytokinesis which divides the cytoplasm. Two genetically identical daughter cells result.
