THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the final step in the cell cycle?
A
Cell grows in the G1 phase
B
Cell divides through mitosis
C
DNA replicates in the S phase
D
Cytoplasm divides through cytokinesis
Explanation: 

Detailed explanation-1: -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-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: -Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.

Detailed explanation-4: -At the final stage of cytokinesis, in a process termed abscission, this bridge is cleaved, and two daughter cells are formed. At the midbody, several cytokinesis-coupled events converge, including degradation of cell cycle regulators, cytoskeleton rearrangements, membrane traffic, and plasma membrane remodeling.

Detailed explanation-5: -Cytokinesis (/ˌsaɪtoʊkɪˈniːsɪs/) is the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis.
