Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
DEFINE:What is cytokinesis
A
the first stage of the cell cycle
B
final stage of the cell cycle
C
stage of the cell cycle during which the cell’s nucleus divides
D
process in which DNA is copied
Explanation: 

Detailed explanation-1: -Cell division ends as the cytoplasm divides into two by the process of cytokinesis. Except for plants, cytokinesis in eucaryotic cells is mediated by a contractile ring, which is composed of actin and myosin filaments and a variety of other proteins.

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 is the final stage of cell division in eukaryotes as well as prokaryotes. During cytokinesis, the cytoplasm splits in two and the cell divides. The process is different in plant and animal cells, as you can see in Figure 7.3. 8.

Detailed explanation-4: -Cytokinesis means the process of division of cytoplasm. Division. The nucleus gets divided into two daughter nuclei. The cytoplasm, cell organelles and the nuclei divide and are passed on to daughter cells equally.

Detailed explanation-5: -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.
