Centrioles, organelles that organize the microtubule spindle required for cell division, duplicate at almost exactly the same time that DNA replicates during the cell cycle. New research points to ...

Two recent studies in Drosophila demonstrate that overexpression of proteins required for centriole duplication can not only induce centriole over-duplication in cells containing centrioles ...

A centriole is a cylindrical structure within ... for each step—e.g., "Interphase," Interphase I"—are those used in biology textbooks.

A real-time recording of starfish egg formation reveals how the cell expels its centrioles—structures involved in cell division labeled mother (green) or daughter (purple)—prior to fertilization.
