Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cytokinesis begins during which phase of mitosis?
A
prophase
B
anaphase
C
metaphase
D
telophase
Explanation: 

Detailed explanation-1: -Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase. A ring of protein filaments called the contractile ring forms around the equator of the cell just beneath the plasma membrane.

Detailed explanation-2: -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-3: -Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Detailed explanation-4: -The final two events of M phase are the re-forming of the nuclear envelope around the separated sister chromatids and the cleavage of the cell. These events occur in telophase and cytokinesis, respectively.
