The property of dynamic instability implies that the individual protein subunits of microtubules are held together by what type of bonds?

Complete question: The property of dynamic instability implies that the individual protein subunits of microtubules are held together by what type of bonds?

a) Disulfide bonds

b) Covalent bonds

c) Non-covalent bonds

d) Microtubule subunits are help together by a combination of all of these bonds.

c) Non-covalent bonds

Explanation:

Microtubules are the hollow cylindrical structures and are polymers of tubulin proteins. Tubulin protein has two subunits called alpha and beta-tubulin. The tubulin subunits are held together by weak noncovalent bonds. This allows their quick polymerization to form spindle during prophase. Since individual proteins subunits are held together by weak interactions, microtubules are quickly depolymerized to facilitate the shortening of spindle fibers during anaphase of cell division.
