Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the last thing that happens during mitosis?
A
The cytoplasm divides
B
The nucleus separates
C
The DNA condenses
D
The sister chromatids separate
Explanation: 

Detailed explanation-1: -Cytokinesis is the final stage of cell division in eukaryotes as well as prokaryotes. During cytokinesis, the cytoplasm splits in two and the cell divides.

Detailed explanation-2: -Cell division ends as the cytoplasm divides into two by the process of cytokinesis.

Detailed explanation-3: -The transition from metaphase to anaphase is triggered by breakage of the link between sister chromatids, which then separate and move to opposite poles of the spindle. Mitosis ends with telophase, during which nuclei re-form and the chromosomes decondense.

Detailed explanation-4: -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). A multinucleated cell is one with several nuclei.

Detailed explanation-5: -In cytokinesis, the cytoplasm of the cell is split in two, making two new cells. Cytokinesis usually begins just as mitosis is ending, with a little overlap. Importantly, cytokinesis takes place differently in animal and plant cells. Cytokinesis in animal and plant cells.
