Miescher
Miescher isolated "nuclien" DNA with its associated proteins from cell nuclei, and he was first to identify DNA as a distinct molecule. -
Griffith
Frederick Griffiths experiment was the first experiment suggesting that bacteria was capable of transferring genetic information. This process is known as transformation. -
Avery
Oswald Avery conducted a series of experiments to show that DNA was not a protein ( at the time people thought it was a protein ) but was a molecule that is responsible for bacterial transformation and the molecule of heredity. -
Chargaff
Erwin Chargaff discovered that amounts of adenine and thymine in DNA were roughly the same, as were the amounts of cytosine and guanine. This is known as the Chargaff's Rule. -
Franklin & Wilkins
Rosalind Franklin and Maurice Wilkins were the first to discover the shape of DNA. They found out that DNA is in a double helix shape. -
Hershey & Chase
Alfred Hershey and Martha Chase conducted a series of experiments that helped to confirm that DNA is a genetic material. -
Watson & Crick
Watson and Crick study about the structure of DNA and found that this molecule contained heredity information.
