The centromere is perhaps the most iconic feature on a eukaryotic chromosome. An amateur enthusiast equipped with a light microscope can easily identify the center of each metacentric chromosome, marking the spot responsible for accurate genome segregation. This review will highlight findings that provide novel insights into how centromeres are assembled and disassembled, the role centromeric proteins play in repair, epigenetic features uniquely found at the centromere, and the three dimensional organization of centromeres caught in the act of mitosis. These advances have unveiled a veritable wonderland of non-canonical features that drive centromere function.

In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a microtubule array...
