Microtubules are hollow rods made of a globular protein called tubulin. each tubulin protein is a dimer made of two subunits. these are easily assembled and disassembled. what are four functions of microtubules?

Microtubules are the tubular polymers of tubulin, which develop the component of the cytoskeleton that offers the cytoplasm of certain bacteria and eukaryotic cells with the shape and composition.  

The four prime functions of microtubules are:  

1. Shape and support the cell.  

2. Accumulate or relate the tubulin dimers.  

3. Distinguishes chromosomes at the time of cellular division.  

4. Function as track along that helps the organelles equipped with motor proteins to move.
