cytokinesis
The breakdown of the nuclear membrane during mitosis allows for the separation of replicated chromosomes into two daughter cells. This ensures proper distribution of genetic material and accurate cell division. It also allows for the formation of the mitotic spindle, which helps in segregating the chromosomes.
Vincristine disrupts the formation and function of the mitotic spindle by binding to tubulin, a protein that helps in spindle formation. This interferes with the normal process of cell division, leading to mitotic arrest and ultimately cell death.
Human mitotic cells undergo cell division to produce two identical daughter cells with the same number of chromosomes as the parent cell. In contrast, human meiotic cells undergo two rounds of cell division to produce four haploid daughter cells with half the number of chromosomes as the parent cell. Meiotic cells are involved in the formation of gametes (sperm and egg cells) for sexual reproduction, while mitotic cells are involved in growth, repair, and asexual reproduction.
Cytokinesis takes place after the other three mitotic events (prophase, metaphase, anaphase) have occurred. Cytokinesis involves the physical separation of the two daughter cells following the division of the genetic material in anaphase.
Formation of 4 haploid nuclei
Telophase is the stage of mitosis characterized by the disintegration of mitotic spindles and the formation of two new nuclear membranes around the two sets of separated chromosomes. During telophase, the chromosomes begin to decondense and the cell prepares for cytokinesis, where the cytoplasm divides to form two daughter cells.
Amitosis is a type of cell division that occurs without the formation of a mitotic spindle and without the typical separation of the nucleus or cytoplasm. It is a rare form of cell division that is primarily observed in bacteria and some cells of lower eukaryotes. Amitosis does not contribute to genetic variation as it results in the formation of identical daughter cells.

Prophase occurs during the first stage of the cell cycle, which is the mitotic phase. It is characterized by the condensation of chromatin into visible chromosomes, the disintegration of the nuclear envelope, and the formation of the mitotic spindle.

Two identical daughter cells are formed as a result of mitotic division. Each daughter cell is a replica of the parent cell with the same number of chromosomes.
