The ability of microtubules to undergo rapid <u>depolymerization </u>and slower<u> polymerization</u> is associated with the ability of the <u>spindle apparatus</u> to explore the cell and locate chromosomes.
<u>Explanation:</u>
Microtubules are tubulin polymers that make up part of the cytoskeleton and provide eukaryotic cells with framework and shape. These are formed by polymerizing the dimer into protofilaments of two globular proteins, alpha and beta tubulin, which can then be combined laterally to form the microtubule, a hollow tube.
Tubulin dimers can attach two GTP molecules, one of which may be hydrolyzed following assembly. Tubulin dimers are in GTP-bound state throughout polymerization. Once hydrolysis reaches to the peak of the microtubule, a rapid depolymerization and shrinkage is initiated.
