Which stage of the cell cycle would the nurse recognize as most critical to the development of genetic changes?
1. G0
2. G1
3. S
4. Interphase
3
Rationale 1: G0 is a permanent resting phase, so no further cell division occurs.
Rationale 2: Gap 1 or G1 is the phase in which most of the cell's metabolic activity occurs. Genetic changes do not occur in this phase.
Rationale 3: The synthesis or S phase is the stage in which DNA replication occurs. If replication is faulty, genetic changes may result.
Rationale 4: Interphase is a resting phase.
