WebCyclins and Cdks drive the cell cycle specific to each phase. Radiation induces cell cycle checkpoints primarily at G 1 and G 2. In cells with intact p53, p21 is induced, which inhibits cdk2 and blocks cells in G 1. In the absence of p53, the G 2 checkpoint is induced by a variety mechanisms that act on cyclin B and cdc2 (also known as cdk1). WebLegend. The primary G1/S cell cycle checkpoint controls the commitment of eukaryotic cells to transition through the G1 phase to enter into the DNA synthesis S phase.
