All cytoskeletal filaments are held together via weak noncovalent interactions, so that assembly and disassembly can occur rapidly is True.
The actin cytoskeleton is constantly assembling and disassembling. Cells harness the energy of these turnover dynamics to drive cell motility and organize cytoplasm.
Although much is known about how cells control actin polymerization, we do not understand how actin filaments depolymerize inside cells.
