Category:GO:0022403 ! cell cycle phase

name: cell cycle phase
namespace: biological_process
def: "One of the distinct periods or stages into which the cell cycle is divided. Each phase is characterized by the occurrence of specific biochemical and morphological events." [GOC:mtg_cell_cycle]
comment: Note that this term should not be used for direct annotation. If you are trying to make an annotation to x phase, it is likely that the correct annotation is 'regulation of x/y phase transition' or to a process which occurs during the reported phase (i.e mitotic DNA replication for mitotic S-phase). To capture the phase when a specific location or process is observed, the phase term can be used in an annotation extension (PMID:24885854) applied to a cellular component term (with the relation exists_during) or a biological process term (with the relation happens_during).
