CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or False. After a cell goes through cytokinesis, it starts the cell cycle all over again.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Mitosis goes through cytokinesis once and meiosis goes through cytokinesis twice. This statement is true. Mitosis only has one round of division where the cytoplasm will divide only once. However, meiosis has two rounds of division, where there will be two cytoplasmic division events.

Detailed explanation-2: -When cytokinesis finishes, we end up with two new cells, each with a complete set of chromosomes identical to those of the mother cell. The daughter cells can now begin their own cellular “lives, ” and – depending on what they decide to be when they grow up – may undergo mitosis themselves, repeating the cycle.

Detailed explanation-3: -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-4: -In cytokinesis, the cytoplasm of the cell is split in two, making two new cells. Cytokinesis usually begins just as mitosis is ending, with a little overlap. Importantly, cytokinesis takes place differently in animal and plant cells. Cytokinesis in animal and plant cells.

Detailed explanation-5: -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.
