How Did Meselson & Stahl Prove DNA Replication? - Biology For Everyone

How Did Meselson & Stahl Prove DNA Replication? Have you ever wondered how scientists prove the way DNA copies itself during cell division? In this fascinating video, we'll explain the clever experiments that unlocked this mystery. We'll start by discussing the challenge scientists faced in understanding DNA replication and why it was so important for genetics. You'll learn about the innovative use of heavy nitrogen and how it helped scientists distinguish between different models of DNA copying. We’ll also explore the technique called density gradient centrifugation and how it allowed researchers to observe the different types of DNA molecules. Additionally, we’ll explain how the results supported the semiconservative model of DNA replication, a key discovery that confirmed the structure of DNA and how genetic information is passed down. Whether you're a student, teacher, or just curious about biology, this video will give you a clear understanding of one of the most important experiments in molecular biology.
