MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which mitosis phase is described? *Cell membrane pinches in half *Two daughter cells form, identical to the original cell *Chromosomes return to chromatin, and daughter cells begin interphase
A
interphase
B
prophase
C
telophase
D
cytokinesis
Explanation: 

Detailed explanation-1: -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. In animal cells, the plasma membrane of the parent cell pinches inward along the cell’s equator until two daughter cells form.

Detailed explanation-2: -Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells.

Detailed explanation-3: -Cytokinesis. Cytokinesis is the second part of the mitotic phase during which cell division is completed by the physical separation of the cytoplasmic components into two daughter cells.

Detailed explanation-4: -Cytokinesis is the final stage in the cell cycle. The cytoplasm pinches in half and separates the nuclei into two daughter cells.

Detailed explanation-5: -The second phase of mitosis is metaphase, in which the chromosomes move into the equatorial plane of the spindle. As the third phase-anaphase-begins, the chromatids separate and move to opposite ends of the cell. Once the chromatids separate, they are called chromosomes.
