Oswald Avery

Oswald Avery was a scientist who, in the 1940s, made a groundbreaking discovery in biology. He identified DNA as the material responsible for carrying genetic information in living organisms, confirming that DNA, not proteins, is the blueprint for heredity. His work built on earlier experiments and helped set the stage for the discovery of DNA’s structure and its role in inheritance. Avery’s research fundamentally changed our understanding of genetics and laid the foundation for modern molecular biology.
