Preferred term	G2 Phase Cell Cycle Checkpoints
Entry term(s)	Checkpoint, G2 Phase Checkpoints, G2 Phase G2 Cell Cycle Checkpoints G2 Phase Checkpoint G2 Phase Checkpoints

G2-M Cell Cycle Checkpoint - Narrower

Concept UI	M0550572
Preferred term	G2-M Cell Cycle Checkpoint
Entry term(s)	G2 M Cell Cycle Checkpoint

G2 Cell Cycle Control - Related but not broader or narrower
