The dynamic structures

Microtubules are highly dynamic structures that continuously break down and reform. They are a tube kind of structure and provide pathways for vesicles to move. For example, a nerve cell form within the cell body and then move through the axon, which has a special structure. To transport the vesicles through the microtubules, this molecule needs support.  proteins such as dynamin help the vesicles to reach the final destination.    also, play a major role in cell division. They form mitotic spindles and without cells division is not possible in animal cells. These microtubules are made up of [tubulin-dimer]. GTP stabilise this         .
