Guided Notes

Key concepts students will learn:

  • The cell cycle has two main phases: interphase, where the cell grows and replicates DNA, and M phase, where the cell divides.

  • During interphase, the cell cycle progresses through G1, S, and G2 phases, with checkpoints to ensure proper growth and DNA replication.

  • Cancer can result from cells dividing too frequently due to a failure in cell cycle regulation, potentially leading to tumor formation.
