Spindle fibre is made up of

Step-by-step solution

'Tubulin' is a cytoskeletal globular protein that polymerizes to form microtubules. It plays a motile and contractile role in cell structure and cell division. During cell division, the microtubules radiate from each end of the cell form a basket like arrangement (the spindle) which helps in the movement of chromosomes to poles. The principal protein of cilia and flagella is also tubulin. Microtubules play a key role in the movement of cilia and flagella. Intermediate filaments are tough rope-like bundles or protei
