Question

Cilia are composed of microtubules. How are microtubules different from the other cytoskeletal filaments?

Answer 1

Answer:

They are thick, strong and made up of thousands of tubulin which are spiral in shape.

Explanation:

In eukaryotic cells, they have microtubules which are fibres serving as tracks for cell to cell transport and regulate the shape of a cell.

Microtubules are different from other cytoskeletal filaments because they possesses a cylindrical shape with the tube having a larger diameter of 20-25 nm as compared to microfilament that have a diameter of 3-6 nm.

Microtubules are made of subunits of proteins called tubulin named alpha and beta that is not present in other cytoskeletal filaments.
