Anaphase Promoting Complex

The Anaphase Promoting Complex (APC) is a crucial protein system in cell division that helps ensure the cell divides correctly. Its main role is to trigger the separation of sister chromatids (replicated chromosomes) during mitosis, allowing each new cell to receive an identical set of chromosomes. The APC activates this process by tagging specific proteins for destruction, which removes the "hold" preventing the chromatids from separating. This precise timing ensures proper division, maintaining genetic stability. In essence, the APC acts as a molecular "trigger," coordinating the final steps of cell division smoothly and accurately.
