centriole

[ sen-tree-ohl ]

noun

, Cell Biology.

1. a small, cylindrical cell organelle, seen near the nucleus in the cytoplasm of most eukaryotic cells, that divides in perpendicular fashion during mitosis, the new pair of centrioles moving ahead of the spindle to opposite poles of the cell as the cell divides: identical in internal structure to a basal body.

centriole

/ ˈsɛntrɪˌəʊl /

noun

1. either of two rodlike bodies in most animal cells that form the poles of the spindle during mitosis

centriole

/ sĕn′trē-ōl′ /

1. Either of a pair of cylinder-shaped bodies found in the centrosome of most eukaryotic organisms other than plants. During cell division (both mitosis and meiosis), the centrioles move apart to help form the spindle, which then distributes the chromosomes in the dividing cell.

Example Sentences

This work, published in the journal Cell, elucidates the complexities of centriole assembly.

From Science Daily

All eukaryotes have the exact same set of organelles familiar to anyone who has studied cell biology: nucleus, nucleolus, ribosomes, rough and smooth endoplasmic reticulum, Golgi apparatus, cytoskeleton, lysosome and centriole.

From Scientific American

Until a few years ago, it was impossible to visualise the structure of the centriole in detail.

From Science Daily

This unique approach, which combines the very high resolution of expansion microscopy and kinematic reconstruction, has enabled us to model the first 4D assembly of the human centriole.

From Science Daily

Obtaining images of the centriole with such high resolution enables the exact location of proteins at a given time but gives no information on the order of appearance of substructural domains or of individual proteins.
