In 1952, Alfred Hershey and Martha Chase conducted a groundbreaking experiment that settled one of biology's greatest debates: Is DNA or protein the genetic material? Using a clever blend of bacteriophages, radioactive isotopes, and a kitchen blender, they revealed DNA as the molecule that carries life’s instructions. This discovery revolutionized molecular biology, paving the way for modern genetics and biotechnology. Explore the fascinating story of their work, the science behind it, and its enduring impact on our understanding of life.
