Which of the following functions is carried out by cytoskeleton in a cell?

An elaborate network of fi lamentous, proteinaceous structures consisting of microtubules, microfi laments and intermediate fi laments present in the cytoplasm is collectively referred to as the cytoskeleton. The cytoskeleton in a cell is involved in many functions, such as mechanical support, motility and maintenance of the shape of the cell.
(1) Cytoskeleton does not play a signifi cant role in transportation.
(2) Nuclear division is not a function of cytoskeleton.
(3) Cytoskeleton has no role in protein synthesis.
