| 11. | A nonfunctioning centriole lies adjacent to the kinetosome.
|
| 12. | These complexes are then anchored at the centriole to begin formation of the centrosome.
|
| 13. | They undergo closed mitosis without centrioles, and typically have mitochondria with flat cristae.
|
| 14. | The environment suitable for procentriole formation is provided by the base of each centriole.
|
| 15. | Centrioles may also be associated in the formation of a spindle during nuclear division.
|
| 16. | Three Cdk2 substrates have been proposed to be responsible for regulation of centriole duplication.
|
| 17. | Centrosome disorientation refers to the loss of orthogonality between the mother and daughter centrioles.
|
| 18. | Centrioles are present in the cells of most eukaryotes, for example those of animals.
|
| 19. | They further show that if the centrioles are not eliminated, those mothers are sterile.
|
| 20. | Centrioles start duplicating when DNA replicates.
