You are studying cell cycle progression in an early frog embryo.If you were to inject a protein synthesis inhibitor into a cell during S phase,where do you predict that the cells would arrest? A)G₁ B)G₂ C)Metaphase D)Telophase

Question

Quizplus · Accepted Answer

The S phase is the phase of the cell cycle where DNA replication occurs. Therefore, if a protein synthesis inhibitor is injected into a cell during S phase, the cell will not be able to complete DNA replication and will likely arrest in the subsequent G2 phase. Option B (G₂) represents a cell in G2 phase, which is the correct prediction for arrest. The other options do not represent the correct phase of the cell cycle where arrest is expected.
