Scientists Timeline.

  • Mendel

    Gregor Mendel was an Australian monk who discovered the basic principles of heredity. Mendel's observations became the foundation of modern genetics. He did all of this in his garden experimenting on pea plants.
  • Friedrich Miescher

    Friedrich Miescher was born in Basel, Switzerland. Friedrich Miescher isolated nuclein DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule.
  • Griffith

    He showed that Streptococcus pneumonia, implicated in many cases of lobar pneumonia, could transform from one strain into a different strain.His discovery was one of the first to show the central role of DNA in heredity.
  • Avery

    Avery was a Canadian American physician and medical researcher. Avery isolated that DNA as a material of which genes and chromosomes are made. These experiments paved the way for Watson and Crick's discovery of the helical structure of DNA
  • Edwin Chargaff

    Erwin Chargaff proposed two main rules in his lifetime which were appropriately named Chargaff's rules.
  • Rosalind Franklin

    She is best known for her work on the X-ray diffraction images of DNA. She discovered that DNA is a double helix polymer.
  • Hershey and Chase

    Hershey and chase concluded that DNA, not protein was the genetic material. They conducted several experiments but the most famous experiment was the Waring Blender experiment.
  • Watson and Crick

    Watson and Crick worked together on studying the structure of DNA, the molecule that contains the hereditary information for cells
  • Collins and Venter

    Venter discovered the genes associated with a number of diseases and led the Human Genome Project. Collins work at Michigan would earn him a reputation as one of the world's foremost genetics researchers.
