CELL DIVISION

THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cytokinesis is a phase of mitosis.
A
True
B
False
Explanation: 

Detailed explanation-1: -Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase.

Detailed explanation-2: -Answer and Explanation: Mitosis goes through cytokinesis once and meiosis goes through cytokinesis twice. This statement is true.

Detailed explanation-3: -Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis. All phases of mitosis, as well as the flanking periods of interphase and cytokinesis before and after, are shown in Figure 8.

Detailed explanation-4: -The correct answer is (a) True. Cytokinesis occurs after mitosis or meiosis, which separates the genetic material of a cell as it divides. Once the genetic material is separated, cytokinesis occurs to split the cytoplasm of the cell into two separate cells.

Detailed explanation-5: -Mitosis can be divided into five distinct stages-prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis, which begins during anaphase or telophase (depending on the cell), is part of the M phase, but not part of mitosis.
