Abstract
Because of their genetic tractability, much has been learned concerning the mechanisms of chromosome segregation in budding yeast, Saccharomyces cerevisiae, and fission yeast, Schizosaccharomyces pombe. This chapter reviews the cytology and molecular and cell biology of mitosis in both of these yeasts. Current knowledge about the components of the mitotic spindle apparatus, including spindle pole bodies, centromeres, and microtubule components and motors, is summarized. Mechanisms of mitosis such as establishment and positioning of the mitotic spindle apparatus, anaphase A, and anaphase B are reviewed.
