"WebDifferent cyclins are expressed in different periods in the cell cycle. In mammalian cells, cyclin A begins to express and gradually accumulate in the early G1 phase, reaching the G1/S junction, and the content reaches the maximum and remains in the G2/M phase. Cyclin B is expressed from the late G1 phase and gradually accumulates. " - Cycline g1
