MICROANATOMY

Detailed explanation-1: -Microtubules are highly dynamic and will frequently grow and shrink at a rapid yet constant rate. During this phenomenon, known as ‘dynamic instability’, tubulin subunits will both associate and dissociate from the plus end of the protofilament [3].

Detailed explanation-2: -In microtubules, GTP hydrolysis also results in the behavior known as dynamic instability, in which individual microtubules alternate between cycles of growth and shrinkage (Figure 11.38). Whether a microtubule grows or shrinks is determined by the rate of tubulin addition relative to the rate of GTP hydrolysis.

Detailed explanation-3: -Microtubules are also highly dynamic, undergoing rapid cycles of polymerization and depolymerization in a process known as dynamic instability. Microtubules emanate from a microtubule organizing centre (MTOC) where their minus end is embedded and the plus end grows towards the cell periphery.
