  • Friedrich Miescher

    Friedrich Miescher
    He isolated nuclein from the cell nuclei. He also identified DNA as a distinct molecule. He went to school at the University of Basel in Switzerland

  • Frederick Griffith

    Frederick Griffith
    He showed how bacteria can get DNA through transformation. He died in his apartment when he was 64

  • Oswald Avery, Maclyn McCarty and Colin McCleod

    Oswald Avery, Maclyn McCarty and Colin McCleod
    They started working on there experiment in 1932 because of Griffith’s experiment.

  • Erwin Chargoff

    Erwin Chargoff
    He showed how the number of Guanine units and cytosine units are the same and how the number of adenine units and thymine units are the same. He is an immigrant that immigrated during World War 2

  • Barbara McClintock

    Barbara McClintock
    She discovered that genes could moves and do not have to stay in place. She received her PhD from Cornell University

  • Alfred Hershey and Martha Chase

    Alfred Hershey and Martha Chase
    They discovered that DNA carries genetic material. Hershey just did science for fun originally.

  • Linus Pauling

    Linus Pauling
    He discovered the spiral structure of proteins that Watson and Crick eventually used to find the structure of DNA
    As well as being a scientist he was also a peace advocate and author

  • Rosalind Franklin and Maurice Wilkins

    Rosalind Franklin and Maurice Wilkins
    Helped discover DNA’s structure and how characteristics are passed down through generations. Wilkins gave Watson and Crick Fanklin's discoveries behind her back

  • James Watson and Francis Crick

    James Watson and Francis Crick
    Found DNA’s structure using Franklin and Wilkins information
    Watson won the nobel peace prize in physiology

  • Fredrick Sanger

    Fredrick Sanger
    He proved that proteins were ordered molecules and by analogy, and genes in DNA mean these proteins should have a sequence too. He won 2 nobel peace prizes.

  • Mathew Meselson and Franklin Stahl

    Mathew Meselson and Franklin Stahl
    They figured out that DNA is replicated semi-conservatively
    Franklin Stahl has had a book called, “The Mechanics of Inheritance”

  • Paul Berg

    Paul Berg
    He made the first hybrid DNA by inserting bacteria DNA to a virus’ DNA.
    He won a nobel peace prize for his work

  • Kary Mullis

    Kary Mullis
    He discovered the process PCR in which a little amount of DNA can be replicated into a large amount. He did odd experiments since he was a teenager

  • J. Craig Venter

    J. Craig Venter
    He lead the first half of the draft sequence of the human genome. He is also a businessman.
