Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cytokinesis occurs at the same time as or immediately following ____
A
telophase
B
anaphase
C
prophase
D
metaphase
Explanation: 

Detailed explanation-1: -Cytokinesis begins in anaphase and ends in telophase, reaching completion as the next interphase begins. The first visible change of cytokinesis in an animal cell is the sudden appearance of a pucker, or cleavage furrow, on the cell surface.

Detailed explanation-2: -Telophase and Cytokinesis 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-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 usually occurs at the same time as telophase I, forming two haploid daughter cells.

Detailed explanation-5: -The difference between cytokinesis and telophase is that cytokinesis is the final step of cell division while telophase is the final step of karyokinesis. Note: Cytokinesis and telophase are steps of cell division. The similarity between both these steps are, 1)Both of them occur in meiosis and mitosis as well.
