A Brief History of Genetics:
From Classical to Molecular



     Classical Genetics (Chapters 14 & 15)

w   Gregor Mendel

   Discovered the basic laws of genetics

   Published a scientific paper about his pea plant experiments  in 1865 that was unrecognized for its brilliance

   Died an unappreciated “genius”- like Van Gogh

   His work was rediscovered 35 years later in 1900



     Molecular Genetics (Chapters 16-20)

w   James Watson and Francis Crick

   Discovered the structure of DNA

   Published a scientific paper in 1953 which identified DNA as a double helix.

s   This lead to the realization that DNA was the molecule of heredity.
