NEET BIOLOGY

Detailed explanation-1: -Cytokinesis is the final step of mitosis in which the contents of the cell (cytoplasm and nuclei) are separated into two distinct, identical daughter cells. Mitosis without cytokinesis results in a cell with more than one nucleus but a connected cytoplasm (syncytium).

Detailed explanation-2: -Cytokinesis failure leads to both centrosome amplification and production of tetraploid cells, which may set the stage for the development of tumor cells.

Detailed explanation-3: -Result: Hence, the formation of two daughter cells that are identical to parental cells is the result of mitosis and cytokinesis.

Detailed explanation-4: -Answer and Explanation: If cytokinesis happened before mitosis, the two resulting cells wouldn’t each have full sets of identical chromosomes. Cytokinesis is the physical division of the parent cell after the process of mitosis has taken place, thus producing two new daughter cells with full sets of chromosomes.

Detailed explanation-5: -When cytokinesis finishes, we end up with two new cells, each with a complete set of chromosomes identical to those of the mother cell. The daughter cells can now begin their own cellular “lives, ” and – depending on what they decide to be when they grow up – may undergo mitosis themselves, repeating the cycle.
