Cdks and the Drosophila cell cycle

Cyclin-dependent kinases play essential roles in driving the cell cycle. Much progress has been made in Drosophila over the past year in identifying the specific requirements for individual cyclins in particular cell cycle events. These studies encompass many aspects of the cell cycle, from the addition of a G1 phase to the cell cycle during embryogenesis to the role of cyclin degradation in progression through anaphase.
