Step 2: Understanding the G^2 Checkpoint
The G^2 checkpoint is a critical control point in the cell cycle that occurs between the S phase (DNA synthesis) and M phase (mitosis). Its primary function is to ensure that: - DNA replication has been completed accurately - Any DNA damage has been repaired - The cell is ready to enter mitosis
Final Answer
If a cell with a mutation at its G^2 checkpoint passes to the next stage of the cell cycle, it would likely proceed with mitosis despite having unrepaired DNA damage or incomplete DNA replication. This could result in genomic instability, production of genetically abnormal daughter cells, and an increased risk of cellular dysfunction or potential cancerous transformation.
