Question

Cytoskeletal filaments that display "dynamic instability:"

Answer 1

Answer:

c. change in length due to polymerization or depolymerization.

Explanation:

Microtubules are the most rigid components of the cytoskeleton. Their length can range from 15 to 25 nanometers (nm), which far exceeds the scale of the cell. Microtubule rigidity occurs due to the tube structure composed of monomers that are part of these structures.

Microtubules are polarized in the same way as actin filaments, but both polymerization and depolymerization are different, as microtubules have dynamic instability, a process that leads to elongation and shortening of microtubules, causing significant force.
