In eukaryotic animal cells, during which phase does the cytoplasm divide?
a. Telophase
b. Cytokinesis
c. Prometaphase
d. Interphase


Sagot :

Answer: b. Cytokinesis

Explanation: Cytokinesis is the final stage of cell division. After the DNA has been evenly separated between both halves of the parent cell, the parent cell begins dividing itself into two daughter cells. With the help of proteins that pinch the cell to create a cleavage furrow, the parent cell divides its cytoplasm into two daughter cells that share the organelles and DNA of the original parent.

Choice A refers to the stage that occurs directly before cytokinesis. During telophase, the DNA of the parent cell is evenly divided between the two halves of the cell by spindle fibers that finish dragging the chromosomes to their respective halves of the cell.

Choice C refers to the 2nd stage of cell division. During prometaphase, the nuclear envelope of the nucleus dissolves and spindle fibers attach to each chromosome in preparation for movement.

Choice D refers to a stage that occurs before cell division even takes place. During interphase, the cell grows and duplicates its DNA in preparation for future cell division.
