DNA Timetoast

  • Friedrich Miescher

    Friedrich Miescher
    He isolated "nuclein," DNA associated proteins from cell nuclei. Friedrich used white blood cells. Helped pave the pathway for identification of DNA as the carrier of inheritance.

  • Frederick Griffith

    Frederick Griffith
    He showed us that bacteria can distinctly change their function and form through transformation. He experimented on mice with bacterias.

  • Barbara McClintock

    Barbara McClintock
    She discovered transportation and used it to demonstrate that genes are responsible for physical characteristics on and off.

  • Oswald Avery, Maclym McCarty, and Colin McCleod

    Oswald Avery, Maclym McCarty, and Colin McCleod
    They discovered that DNA carries a cell's genetic material and can be altered through transformation. They also experimented on mice, it was similar to Frederick Griffith's experiment.

  • Erwin Chargaff

    Erwin Chargaff
    He discovered rules that in DNA the number of guanine units is equal to the number of cytosine units, and the number of adenine units is equal to the number of thymine.

  • Alfred Hershey and Marsha Chase

    Alfred Hershey and Marsha Chase
    Their experiment proved DNA as genetic material. They used bacteria and cells.

  • James Watson and Frances Crick

    James Watson and Frances Crick
    Watson and Crick discovered the structure of DNA. They yielded new research in genes and DNA.

  • Frederick Sanger

    Frederick Sanger
    He discovered the structure of protein molecules and insulin. He won a Nobel prize.

  • Matthew Meselson and Franklin Stahl

    Matthew Meselson and Franklin Stahl
    They used E. coli DNA to prove that DNA replication is semiconservative.

  • Rosalind Franklin and Maurice Wilkins

    Rosalind Franklin and Maurice Wilkins
    They co-discovered the double-helix structure of DNA. They used X-ray crystallography to discover it

  • Linus Pauling

    Linus Pauling
    He discovered the spiral structure of proteins. It contributed to the discovery of the DNA double helix.

  • Paul Berg

    Paul Berg
    Worked with Sanger on proteins and nucleic acids. He also assisted in the first discovery of recombinant DNA.

  • Kary Mullis

    Kary Mullis
    He invented the polymerase chain reaction, a simple technique that allows a specific stretch of DNA to be copied billions of times in a few hours.

  • J. Craig Venter

    J. Craig Venter
    He lead the first draft sequence of the Human Genome and assembled the first team to transfect a cell with a synthetic chromosome.
