This volume focuses on the structural aspects of cell division, ranging from nuclear envelope breakdown to cytokinesis and partitioning of the cytoplasm. It examines spindle assembly and chromosome behavior in mitosis and meiosis, centromere and kinetochore structure and regulation, telomeres, the role of centrosomes, and mechanisms by which overall regulation is achieved. Written as a companion volume to Cell Cycle Control, this book provides an up-to-date account of developments in this exciting area of cell biology.
