What forms the contractile ring in animal cells?
Understand the Problem
The question is asking about the components that make up the contractile ring during the process of cytokinesis in animal cells. The contractile ring is primarily formed by a band of actin filaments and myosin II, which help in the division of the cell.
Answer
Filamentous actin (F-actin) and myosin-2, along with additional structural and regulatory proteins.
The final answer is the contractile ring is composed of filamentous actin (F-actin) and myosin-2, along with additional structural and regulatory proteins.
Answer for screen readers
The final answer is the contractile ring is composed of filamentous actin (F-actin) and myosin-2, along with additional structural and regulatory proteins.
More Information
The contractile ring plays a crucial role in the final step of cytokinesis, ensuring proper division of the cell into two daughter cells.
Tips
A common mistake is forgetting that other structural and regulatory proteins are involved, not just actin and myosin-2.
