Question

Quizplus · Accepted Answer

Dynamic instability of microtubules is a unique property that allows them to rapidly assemble and disassemble, which is essential for their functions such as cell division, intracellular transport, and cell polarity. It is not caused by the size of microtubules or a deficiency of free tubulin subunits, and other cytoskeletal elements such as intermediate filaments and actin filaments do not share this property.
