Microtubule play important roles in cell division, intracellular transport, cell movement and in the maintenance of cell structure. Microtubules(MTs) are polymers of dimeric alpha and beta tubulins. They are one of the cytoskeletal elements. They provide rigidity to the cell thereby maintaining its shape.
A cell when undergoes the process of cell division there are structures known as spindle fibres that are required to pull the chromosomes off to the poles of the cell so that it can be segregated into the cells properly while division. These spindle fibres are made of microtubules that are protein molecules constituting the cytoskeleton of a cell.
