Source sentences:
text: The “point centromeres” of this organism are built on a single nucleosome with what contains the histone H3 variant CSE4 (CENP-A), the CBF3 DNA-binding complex, and 12 additional proteins already identified (Pluta et al., 1995; Pidoux and Allshire, 2000).
text: Because epigenetic centromere propagation relies on replenishing centromeric nucleosomes, it is expected that their sizes will be larger than those of genetically defined centromeres in S. cerevisiae, which have only a single centromeric nucleosome ().
text: In Saccharomyces cerevisiae, where “point-centromeres” are defined by a single nucleosome, theMAM1 gene product is essential for monopolarity, although noMAM1 homologues have been identified in any other organism (8).
