Microtubules are long, hollow tubes present in each of your cells. They help to maintain the shape of the cell, and they form rails along which material is transported throughout the cell. They even help with the cell division.

In this video https://www.youtube.com/watch?v=YGU0uN_RAIo we show you how microtubules assemble from molecules of proteins randomly scattered throughout every cell. The video has been rendered with a real-time molecular visualization engine Marion and real-time composition library Vj made by nanographics. https://nanographics.at
