Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During which stage of the cell cycle does the cell membrane pinch the cell into two?
A
telophase
B
interphase
C
prophase
D
cytokinesis
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: -Cytokinesis is the physical process that finally splits the parent cell into two identical daughter cells. During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.

Detailed explanation-3: -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-4: -During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

Detailed explanation-5: -At the cytokinesis furrow, it is the actin-myosin contractile ring that drives the cleavage process, during which cell membrane and wall grow inward, which eventually pinches the mother cell in two.
