Which cytoskeletal proteins are important constituents of the contractile structures that form the cleavage furrows involved in animal cell cytokinesis?
A) elastin
B) dynein
C) actin
D) tubulin

Question

Quizplus · Accepted Answer

Actin is a major cytoskeletal protein involved in the formation and contraction of the contractile ring responsible for cytokinesis in animal cells. Elastin is not involved in cytokinesis, dynein is involved in the movement of organelles and vesicles within cells, and tubulin is a major component of microtubules, which are not directly involved in cytokinesis but may play a supporting role in cell division.
