  1. The Molecule of Inheritance

  2. Frederick Griffith Griffith concluded that the killed virulent bacteria had passed on a characteristic to the non-virulent one to make it virulent.  He thought that this characteristic was in the inheritance molecule.  This passing on of the inheritance molecule was what he called transformation.

  3. Oswald Avery     Fourteen years later a scientist named Oswald Avery continued with Griffith’s experiment to see what the inheritance molecule was.  In this experiment he destroyed the lipids, ribonucleic acids, carbohydrates, and proteins of the virulent pneumonia.  Transformation still occurred after this.  Next he destroyed the deoxyribonucleic acid.  Transformation did not occur.  Avery had found the inheritance molecule, DNA!
