DNA Timeline

  • Friedrich Miescher

    he was the first to identify DNA as a distinct molecule. I found it interesting that he discovered this in a university
  • Frederick Griffith

    He made a model showing that bacteria can get DNA through a process called transformation. I find it cool that he did this by himself
  • Oswald Avery, Maclyn McCarty & Colin McCleod

    They showed that DNA was the transforming principle. It changed all the time
  • Barbara McClintock

    She discovered that chromosomes can vary
  • Erwin Chargaff

    He discovered that the proportions of bases in DNA depend on the species the DNA comes from. This is a major breakthrough at the time
  • Linus Pauling

    He became known as the founder of molecular biology due to his discovery of the spiral structure of proteins. I find it interesting that he got a nobel peace prize.
  • Frederick Sanger

    He was working out the amino-acid sequence of cow insulin
  • Alfred Hershey & Martha Chase

    They concluded that protein was not genetic material, and that DNA was genetic material. I find it interesting that they discovered this kind of recently
  • Rosalind Franklin & Maurice Wilkins

    They revealed the physical and chemical basis of how characteristics are passed down through the generations and how they are expressed in individual organisms.
  • James Watson & Frances Crick

    In 1953 they announce they have found the structure for a double helix
  • Matthew Meselson & Franklin Stahl

    They invented the technique of density gradient and used this to prove that DNA is replicated semi-conservatively.
  • Paul Berg

    He was inserting DNA from a bacterium into the virus' DNA. He in turn created hybrid DNA
  • Kary Mullis

    He invented the process known as polymerase chain reaction, in which a small amount of DNA can be copied in large quantities over a short period of time.
  • J. Craig Venter

    He made the first synthetic chromosome
