There are three main checkpoints in the cell cycle. Each checkpoint serves a different purpose and have their certain cyclins present. At the G1 checkpoint, a cell undergoes certain conditions to see if it is prepared for cell division. If a cell receives restrictions from the G1 checkpoint and can not continue into the next phase, what could the cell do next?
A) All cells pass the G1 checkpoint and enter into the next phase.
B) The cell can enter the G0 (resting stage) until conditions can improve.
C) The cell will always go directly into the G2 checkpoint to continue the cell cycle.
D) The cell will directly enter the M phase and all of the errors will be fixed during this phase.
