DNA timeline

  • Friedrich Miescher

    Friedrich Miescher

    He discovered nucleic acid (DNA). He was the first researcher to isolate and identify nucleic acid. Meicher isolated various phosphate-rich chemicals, which he called nucleon.
  • Gregor Mendel

    Gregor Mendel

    He figured out the science of how we inherit character traits from our families.
  • John Sulston

    John Sulston

    Awarded for work done in understanding the development of cells and dividing of cells in C. Elegans.
  • Frederick Sanger

    Frederick Sanger

    He is known for the sequence of insulin by amino acids.
  • Frederick Griffith

    Frederick Griffith

    He did one expieriment he thought would help others point out that DNA is a molecule of inheritance.
  • Erwin Chargaff

    Erwin Chargaff

    Noticed that there was a pattern that occured in the four bases which are: adenine, guanine, cytosine.
  • Oswald Theodore Avery

    Oswald Theodore Avery

    He discovered that DNA is the material of which genes and chromosomes are mad.
  • Maurice Wilkins

    Maurice Wilkins

    He discovered the structures of DNA- make first accurate model of DNA.
  • Hersey and Chase

    Hersey and Chase

    At the Cold Spring Harbor Laboratory showed that the DNA, not the protein, of the phage virus* contains the phage genes. How they made the experiment successful was that they put it in a blender to see if viral infections were affected by the movement.
  • Watson and Crick

    Watson and Crick

    They used Rosalinds x-ray diffraction and helped propose the double helix.
  • Rosalind Franklin

    Rosalind Franklin

    Knowm for her work on X-ray diffraction images of DNA.
  • Thomas Morgan

    Thomas Morgan

    He proved that genes or genetic material is carried on chromosomes by his experiments with fruit flies.
