Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is cytokinesis?
A
This is when two cells merge together to make one giant cell.
B
The stage where chromosomes migrate to the opposite ends of the cell.
C
The stage of the cell cycle where the rest of the cell divides after mitosis is complete.
D
The stage in which DNA condenses into chromosomes.
Explanation: 

Detailed explanation-1: -Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.

Detailed explanation-2: -Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells.

Detailed explanation-3: -Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase.

Detailed explanation-4: -Cytokinesis is generally defined as the division of the cytoplasm during the M phase of the cell cycle. It is the 2nd step in the M phase. This process also cannot occur without karyokinesis. It is generally the final stage of mitosis, whereby cytoplasm & other cell organelles divide between the two daughter cells.

Detailed explanation-5: -Cytokinesis is the division of the cytoplasm. The cytoplasm of the cell is being divided in order to obtain two new daughter cells. How does cytokinesis occur? Cytokinesis occurs in mammalian cell division when a contractile ring of microfilaments generates a cleavage furrow that pinches the cell membrane in two.
