Microtubules

This animation shows the structure and fucntion of microtubules in the cell. Microtubules are conveyer belts inside the cells. They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins. They also serve a cytoskeletal role. Structurally, they are linear polymers of tubulin which is a globular protein. These linear polymers are called protofilaments. The figure to the left shows a three dimensional view of a microtubule. The tubulin molecules are the bead like structures. A protofilament is a linear row of tubulin beads. Text reff: http://cellbio.utmb.edu/cellbio/microtub.htm
