centriole definition in biology
Centriole as an organelle is made use of in organizing the mitotic spindle and completing the cytokinesis. At one point in time, centrioles were believed to be necessary for the creation of mitotic spindle in the cell of animals.
Chemical composition of centriole: The subfibres or microtubules of centriole contain the structural protein, tubulin, and lipid molecules (Fulton, 1971). The centrioles contain a high concentration of ATPase enzyme. Presence of nucleic acid in centrioles is doubtful.
