Centromeres, specialized regions on chromosomes, are essential for accurate chromosome segregation during cell division. In fission yeast, the RNA interference machinery has a pivotal function in the assembly of centromeric heterochromatin, which mediates sister centromere cohesion. Studies in vertebrate cells now suggest that many aspects of this process are conserved.
