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 ...

During this time, chromosomes replicate—each DNA strand unzips into two strands while free-floating ... Two pair of centrioles lie just outside the nucleus, next to each other.
