Final Answer:
Control of actin assembly occurs during various cellular processes, including cell migration, cytokinesis, and the formation of cellular structures like filopodia and lamellipodia. Regulated by signaling pathways and various actin-binding proteins, the control of actin assembly is crucial for dynamic cellular functions.
Step-by-step explanation:
The final answer provides a broad overview, indicating that control of actin assembly is a dynamic process regulated during various cellular activities. It mentions specific cellular processes such as cell migration, cytokinesis, and the formation of cellular structures where actin assembly is actively controlled.
The involvement of signaling pathways and actin-binding proteins underscores the complexity and precision of this regulation in cellular functions.
