Microtubules, microfilaments and intermediate filaments:
| 1. | are ribonucleoproteins. |
| 2. | are part of cytoskeleton in both eukaryotic and prokaryotic cells. |
| 3. | are involved in many functions such as mechanical support, motility, maintenance of the shape of the eukaryotic cell. |
| 4. | are always deposited on cell surface and are never found in the cytoplasm. |

The arrangement of axonemal microtubules in cilia and flagellum is referred to as 9 + 2 array which essentially means that the axoneme has:
| 1. | nine doublets of radially arranged peripheral microtubules and two doublets of centrally located microtubules enclosed by a central sheath. |
| 2. | nine triplets of radially arranged peripheral microtubules and a pair of centrally located microtubules enclosed by a central sheath. |
| 3. | nine triplets of radially arranged peripheral microtubules and a centrally located protein hub not enclosed by a central sheath. |
| 4. | nine doublets of radially arranged peripheral microtubules and a pair of centrally located microtubules enclosed by a central sheath. |
Subtopic: Â Cilia & Flagella |
