Discovery of DNA

By gangster boss 9000

  • 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

    Deciphering of Genetic code
    Formulated Method for Reading DNA
    Answered DNA's Importance to all life

  • Stanley Cohen & Herbert Boyer

    Discovered ability to reconstruct DNA in foreign cells

  • Kary Mullis

    Showed How to replicate DNA, Paving way for DNA Fingerprinting

  • Alec Jeffreys

    discovery of genetic fingerprinting techniques
