Centrioles are cylindrical structures that are composed of groupings of microtubules arranged in a ring of nine triplets. They are found in animal cells and help to organize the assembly of microtubules during cell division. Credit: Stocktrek Images/Getty Images.
Centrioles are built from a cylindrical array of 9 microtubules, each of which has attached to it 2 partial microtubules. The photo (courtesy of E. deHarven) is an electron micrograph showing a cross section of a centriole with its array of nine triplets of microtubules. It is duplicated during S phase of the cell cycle. 2  Just before mitosis, the two centrosomes move apart until they are on opposite sides of the nucleus. 3  As mitosis proceeds, microtubules grow out from each centrosome with their plus ends growing toward the metaphase plate.
