Question

Quizplus · Accepted Answer

Animal cells achieve cytokinesis by forming a cleavage furrow that pinches the cell into two. This is accomplished by the contraction of a ring of microfilaments made of actin and myosin, which constricts the cell membrane and creates two daughter cells. Binary fission and cell plate formation are methods of cytokinesis in prokaryotic and plant cells respectively. Chromosome condensation and elongation are processes involved in mitosis, but not cytokinesis.
