Checkpoints of the Cell Cycle

Explore the critical checkpoints of the cell cycle in this informative biology video. Delve into the intricate mechanisms that regulate cellular division, understanding how these checkpoints ensure the accuracy and integrity of DNA replication and cell growth. Learn about the G1/S checkpoint, the G2/M checkpoint, and the metaphase checkpoint, discovering their roles in preventing errors and maintaining genomic stability. Gain insights into the molecular players involved in these checkpoints, including cyclins, cyclin-dependent kinases, and tumor suppressor proteins. Understand how disruptions in these checkpoints can lead to uncontrolled cell division and potentially contribute to cancer development. Enhance your knowledge of cell biology and prepare for MCAT-level questions related to cell cycle regulation and control mechanisms.
