Discovery of DNA

  • Gregor Mendel

    Discovered fundamental laws of inheritance.
  • Friedrich Miescher

    First to identify DNA a distinct molecule.
  • Albrecht Kossel

    Identified nuclein as a nucleic acid and providing its present chemical name deoxyribonucleic acid (DNA)
  • Nikolai Koltsov

    He thought that DNA was made up of 2 mirror stands that replicate in a semi-conservative fashion.
  • William Astbury

    First to attempt to solve the structure of DNA and took first x-ray photographs of biological macromolecules found with living cells
  • Frederick Sanger

    Researching problems related to the determination of structure of proteins which resulted in the determination of the structure of insulin
  • Erwin Chargaff - Late 40's

    Figured out that the G&C units were the same & the A&T units were the same, which lead to the discovery of the double helix structure.
  • Rosalind Franklin

    Discovered the DNA molecule is shaped like a twisted ladder
  • Maurice Wilkins

    Analysed DNA Molecules Under Microscopes and Spectrophotometas
  • James Watson & Francis Crick

    Discovered the double helix, the twisted- ladder structure of DNA
  • Raymond Gosling

    Co-Authored Papers on Double Helix Strcuture
  • Marshall Nirenberg, Har Gobind Khorana and Robert Holley
