Mikrotubuller
Mikrotubuller are microscopic hollow tubes that are part of the cytoskeleton of eukaryotic cells. They are composed of polymers of tubulin, a globular protein. These dynamic structures play a crucial role in maintaining cell shape, facilitating intracellular transport, and forming essential components of the spindle fibers during cell division. They are also found in cilia and flagella, where they contribute to cell motility.
The assembly and disassembly of mikrotubulles are tightly regulated processes, allowing cells to adapt to changing
