It depicts the many complexes of cyclin and Cdk (cyclin/Cdk) as fulfilling unique and essential steps that dictate the sequential order of cell cycle events. Recent analyses of knockout mice challenge this view. Cdk2 and cyclin E, long thought to be essential, are largely dispensable. Here, we discuss...
