This collection of cutting-edge techniques for the study of the eukaryotic cell cycle and its key regulatory molecules includes overviews of cell cycle regulatory mechanisms in many major research organisms. Described in step-by-step detail, these readily reproducible methods enable fundamental research on well-defined cell cycle regulators-and those more recently defined-in yeasts, bacteria, plants, Drosophila, Xenopus, and mammals. The book offers all cell researchers indispensable techniques essential to understanding how normal cells divide and how this is altered in disease.
