Explore: G1 Phase

The G1 phase, gap 1 phase, or growth 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part

distinct phases: G1 phase, S phase (synthesis), G2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself

extended G1 phase or in a cell cycle phase distinct from G1 – termed G0. Subsequent research pointed to a restriction point (R-point) in G1 where cells

S phase (Synthesis phase) is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication

G1 phase to S phase. Once in the S phase, Cln1 and Cln2 dissociates with Cdc28 and complexes between Cdc28 and Clb5 or Clb6 are formed. In G2 phase,

restriction point (R), also known as the Start or G1/S checkpoint, is a cell cycle checkpoint in the G1 phase of the animal cell cycle at which the cell becomes

methionine, some cells arrest in early G1 phase. S phase follows G1 phase via the G1/S transition and precedes G2 phase in interphase and is the part of the

throughout the cell cycle, but it is critical to DNA repair during the G1 phase. In the G1 phase, there are no sister chromatids present for use by the HR pathway

transitions between phases: Cyclin D and Cdk4/6 are active in the G1 phase, while Cyclin E and Cdk2 are active during the late G1 phase and S phase; and Cyclin

The G1/S transition is a stage in the cell cycle at the boundary between the G1 phase, in which the cell grows, and the S phase, during which DNA is replicated
