Homolog Segregation Depends on <strong>Meiosis</strong>-<br />

Specific, Kinetochore-Associated Proteins<br />

• Kinetochores<br />

– protein complexes associated with the centromeres<br />

• Kinetochores on the two sister chromatids attach to opposite poles of the<br />

spindle<br />

• Segregate into different daughter cells at anaphase<br />

• Arms of the sister chromatids of homologs separate at anaphase I
