The correct answer is: E) cleavage furrow formation and cytokinesis
Cytochalasin B (cytos-cell and chalasis-relaxation) is a molecule which inhibit network formation by actin filaments by blocking monomer addition. As a result, itshortens actin filaments. This molecule is involved in cytoplasmic division where it blocks the formation of contractile microfilaments. One of the microfilament’s function includes cytokinesis and formation of cleavage furrow so these functions are affected by cytochalasin B.
The answer is A because if you want a reliable source of scientific information you should go to an actual scientist at a scientific conference.
