Cell cycleTetrahymena thermophilaThe majority of Tetrahymena thermophila cells in the stationary phase of growth was arrested in their cell cycle at G1 phase by low molecular weight substances released by the cells themselves and accumulated in the culture medium. The experiments for understanding the ...

G1 refers to the first gap of time in the cell cycle and G2 refers to gap number two. The other phases of the cell cycle, S and M, refer to the terms "synthesis" and "mitosis," respectively. Within the G1 phase, the subphases ...
The cell cycle occurs over approximately 24 hours (in a typical human cell) and in two distinct stages: interphase, which includes three phases of the cell cycle (G1, S, and G2), and mitosis (M). During interphase, which takes up about 95 percent of the duration of the eukaryotic cel...

During late S and G2 phases of the cell cycle, Cdk1/Cyclin B is inhibited through threonine (Thr) and tyrosine (Tyr) phosphorylation of Cdk1 by the Wee1 kinase. Dephosphorylation of Cdk1 by the Cdc25 phosphatases (Cdc25A, B, and C) activates MPF to initiate mitosis (Fig. 4). DNA...
The retinoblastoma protein (Rb) has traditionally been associated with regulating the progression of cells through the G1 restriction checkpoint of the cell cycle. There is increasing evidence that Rb is also involved in controlling the progression of cells through S phase. We have evidence that Rb...
the cell decides whether it proceeds with the rest of the phases of the cell cycle or leave the cell cycle. If the cell receives a signal to keep it at an un-dividing stage, the cell will not enter into the S phase. It will move into the dormant phase called G0 phase. G0 phase ...
Here we show that cells expressing p27T187A were unable to downregulate p27 during the S and G2 phases of the cell cycle, but that this had a surprisingly modest effect on cell proliferation both in vitro and in vivo. Our efforts to explain this unexpected result led to the discovery ...
