Tripartite organization of centromeric chromatin in budding yeast

The centromere is the genetic locus that organizes the proteinaceous kinetochore and is responsible for attachment of the chromosome to the spindle at mitosis and meiosis着丝粒（centromere）是一类遗传位点，其能够组装形成蛋白质复合物动粒（kinetochore），并介导染色体在有丝分裂与减数分裂过程中与纺锤体的附着。
