Given below is an electron microscopic structure of:
1. | Cilium | 2. | Flagellum |
3. | Fimbria | 4. | Centriole |
Which statements are correct regarding centriole?
I: | Centrioles are typically made up of nine sets of short microtubule triplets, arranged in a cylinder. |
II: | The main function of centrioles is to produce cilia during interphase and the aster and the spindle during cell division. |
III: | Centrioles start duplicating when DNA replicates. |
1. | Only I and II | 2. | Only I and III |
3. | Only II and III | 4. | I, II and III |
