How DNA Replicates and Repairs Itself

Miacademy & MiaPrep Learning Channel

This comprehensive biology video breaks down the complex process of DNA replication, explaining how cells faithfully copy their genetic material before division. Using the analogy of copying tedious math formulas, the narrator introduces the sheer scale of cellular division in the human body—approximately 10 quadrillion times in a lifetime. The video visually demonstrates the semi-conservative nature of replication, where the double helix unwinds and unzips to create templates for new strands, ensuring genetic continuity.
