While absent in prokaryotes, pairs of these structures migrate to opposite ends of eukaryotic cells at the start of mitosis and help anchor the spindle fibers that attach to the chromosome's centromere.
They are composed of nine sets of microtubule triplets arranged in a ring structure, and they are usually arranged at right angles to each other. It was recently proven that their absence during cell division does not affect the formation of the spindle apparatus. While absent in prokaryotes, pairs of these structures migrate to opposite ends of eukaryotic cells at the start of mitosis and help anchor the spindle fibers that attach to the chromosome's centromere. FTP, identify these cylindrical structures that help organize microtubule assembly during mitosis.
