During which phase, a cleavage furrow is formed in animal cells?

ANS:A - C

In cell biology, the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process cell division. The same proteins responsible for muscle contraction, actin and myosin, begin the process of forming the cleavage furrow. Other cytoskeletal proteins and actin binding proteins are involved in the procedure.
