    Friedrich Meischer

    He isolated nuclein from the cells nuclei. he was the first to identify DNA as a distinct molecule.
  • Frederick Griffith

    Frederick Griffith

    He made the first experiment suggesting that bacteria transfers genetic material.
  • Oswald Avery, Maclyn McCarty, and Colin McCleod

    Oswald Avery, Maclyn McCarty, and Colin McCleod

    They discovered that genes are made up of DNA. And, they showed that they can transform the properties of cells.
