  • Erwin Chargaff

    Erwin Chargaff
    isolated DNA from differnt organisms and measured the levels of the 4 nitrogen bases
  • Rosalind Franklin

    produced the x-ray crystallography of BDNA. That was also used to determine the structure of double stranded DNA
  • Hershey-Chase

    Hershey-Chase
    Alfred and martha chase did a combined blender experiment that proved phage DNA not protein was the genetic material
  • James Watson

    James Watson
    came up with the structure of DNA, the double helix
  • Francis Crick

    known for the term central dogma or the idea that genetic information flow in cells is one-way. from DNA to RNA to protein.
  • Steve Fodor

    Steve Fodor
    developed a technique called genechip probe arrays. where you can build sequences you want on a screen with special glass
  • Pat Brown

    developed where cDNAs can be put on glass slides to help with large scale studies
