Fofino [41]

Answer:

The correct answer is - end of cytokinesis.

Explanation:

Cytokinesis :- a procedure that partitions the cytoplasm and plasma layer of a cell, bringing about two indistinguishable cells that contain their own DNA, nucleus, nuclear membrane, and plasma membrane.  

During the last phase of the cell cycle, cytokinesis permits the cell to complete the process of isolating, making two cells with indistinguishable duplicates of DNA  

The cell squeezes in the equator area with the assistance of a ring of contractile protein filaments. The formed cleavage furrow develops until the two cells squeeze off totally.

Thus, the correct answer is - end of cytokinesis.
