as the eukaryotic cell cycle is a complex process, eukaryotes have evolved a network of regulatory proteins, known as the cell cycle control system, which monitors and dictates the progression of the cell through the cell cycle. this system acts like a timer, or a clock, which sets a fixed amount of time for the cell to spend in each phase of the cell cycle, while at the same time it also responds to information received from the processes it controls. the cell cycle checkpoints play an important role in the control system by sensing defects that occur during essential processes such as dna replication or chromosome segregation, and inducing a cell cycle arrest in response until the defects are repaired. the main mechanism of action of the cell cycle checkpoints is through the regulation of the activities of a family of protein kinases known as the cyclin-dependent kinases (cdks), which bind to different classes of regulator proteins known as cyclins, with specific cyclin-cdk complexes being formed and activated at different phases of the cell cycle. those complexes, in turn, activate different downstream targets to promote or prevent cell cycle progression.
