The representation of the cell cycle in GO is split into two sections: the physical processes that occur and the temporal stages—prophase, anaphase and so on—used to describe sets of events. This method of representation is used to prevent true path problems when organisms differ from the "canonical" (usually S. cerevisiae) cell cycle.
Terms and Structure
The cell cycle node sits under cellular process ; GO:0007049 and is split into types of cell cycle (meiotic or mitotic) and stages (M phase, S phase, etc.), plus a regulation term.
