Dna discovery.

DNA is the molecular structure of a body. This structure was identified and explained by scientists James Watson and Francis Crick. The discovery of DNA and identification of it’s structure was a major breakthrough in science. It explained a structure that can be applied to cells within the body. The Hershey-Chase experiments. In their now-legendary experiments, Hershey and Chase studied bacteriophage, or viruses that attack bacteria. The phages they used were simple particles composed of protein and DNA, with the outer structures made of protein and the inner core consisting of DNA. Friedrich Miescher (1844–1895) discovered nucleic acids. Modern understandings of DNA have evolved from the discovery of nucleic acid to the development of the double-helix model.
