The property of dynamic instability implies that the individual protein subunits of microtubules are held together by:
A)covalent bonds.
B)disulfide bonds.
C)noncovalent interactions.
D)All of these choices are correct.

Question

Quizplus · Accepted Answer

The property of dynamic instability, which is the ability of microtubules to switch between growth and shrinkage phases, is due to the noncovalent interactions between the individual protein subunits that make up the microtubule structure. Covalent and disulfide bonds would create a more rigid and stable structure, which is not characteristic of microtubules. Therefore, the best choice is C, noncovalent interactions.
