Evolution of DNA Science

  • Oswald Avery

    Oswald Avery
    Conducted an experiment that indeed showed that DNA is where genes and chromosones are made.
  • Erwin Chargaff

    Erwin Chargaff
    Created the "Chargaff Rules" which stated that DNA from any living organism should have a 1:1 ratio of pyrimidine and purine bases, He discovered the double structure of DNA by doing that.
  • Hershey-Chase

    Hershey-Chase
    Used bacteriophases to confirm that DNA was indeed the genetic material.
  • James Watson/ Fancis Crick

    James Watson/ Fancis Crick
    Discovered the molecular structure of DNA through nuclear acids.
  • Rosalind Franklin

    Rosalind Franklin
    Discovered the x-ray diffraction images of DNA which showed a clearer image of the double helix structure of DNA.
  • Marshall Nirenberg

    Marshall Nirenberg
    He created the genetic code
  • Frederick Sanger

    Frederick Sanger
    Created DNA sequencing.
  • Mario Capecci

    Mario Capecci
    Discovered Homologous recombination
  • Steve Fordor

    Steve Fordor
    Developed the gene chip, which displayed the detail of genetics
  • Gregor Mende

    Gregor Mende
    Conducted the pea plant experiments and established the rules of heredity.
