The History Of DNA

Timeline created by Samplingbacon84
  • Gregor Mendel

    Gregor Mendel
    Gregor Mendel discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent.
  • Friedrich Miescher

    Friedrich Miescher
    Friedrich Miescher isolated "nuclein," DNA with associated proteins
  • Frederick Griffith

    Frederick Griffith
    Frederick Griffith was a British bacteriologist. Griffith's famous 1928 experiment showed us that bacteria can distinctly change their function and form through transformation.
  • Oswald Avery

    Oswald Avery
    Avery is best known for the experiment that isolated DNA as the material of which genes and chromosomes are made.
  • Erwin Chargaff

    Erwin Chargaff
    In 1949, Chargaff discovered that the proportions of bases in DNA depend on the species the DNA comes from.
  • Rosalind Franklin

    Rosalind Franklin
    Franklin is best known for her work on the X-ray diffraction images of DNA, particularly Photo 51
  • Hershey & Chase

    Hershey & Chase
    Hershey and Chase concluded that DNA, not protein, was the genetic material.
  • Watson & Crick

    Watson & Crick
    Watson and Crick announce that they have determined the double-helix structure of DNA, the molecule containing human genes.
  • J.Craig Venter

    J.Craig Venter
    Venter is known for leading the first draft sequence of the human genome and assembled the first team to transfect a cell with a synthetic chromosome.
  • Francis Collins

    Francis Collins
    Collins discovered the genes associated with a number of diseases and led the Human Genome Project.
