  • Frederick Griffin

    Frederick Griffin

    Griffin experiment with bacterium was the first to reveal the “transforming principle,” which led to the discovery that DNA acts as the carrier of genetic information.
  • Griffin's experiments on mice which led to the discovery that DNA acts as the carrier of genetic information.

  • Oswald Avery

    Oswald Avery

    Oswald and his group discovered DNA was the "transforming principle." When isolated from one strain of bacteria, DNA was able to transform another strain and confer characteristics onto that second strain. DNA was carrying hereditary information.
  • Oswald's discovery that DNA was carrying hereditary information.

    Oswald's discovery that DNA was carrying hereditary information.

  • Alfred Hershey and Martha Chase

    Alfred Hershey and Martha Chase

    Hershey and Chase discovered that the proportions of bases in DNA depend on the species the DNA comes from.
  • Hershey and Chase's discovery that DNA was genetic material.

    Hershey and Chase's discovery that DNA was genetic material.

  • Erwin Chargaff

    Erwin Chargaff

    Chargaff was the first to accurately measure nucleotide amounts in DNA.
  • Chargaff's nucleotide measurement rule

  • Maurice Wilkins and Rosalind Franklin

    Maurice Wilkins and Rosalind Franklin

    Wilkins and Franklin worked with x-ray crystalography to find more clues about the DNA structure.
