Quizplus · Accepted Answer

The cleavage furrow is formed during cytokinesis, which involves the contraction of a ring of actin and myosin proteins called the contractile ring. This ring pulls the plasma membrane inward, creating a furrow that eventually separates the two daughter cells. Therefore, the correct choice is D, contractile ring. Sister chromatids are involved in DNA replication and segregation, the mitotic spindle helps separate chromosomes during mitosis, and the metaphase plate is involved in aligning chromosomes during metaphase.
