Harold Urey lecturing to a class in the '50s. It was at a lecture like this that Stanley Miller first heard about the idea of synthesizing organic molecules in a pre-biotic world.
Stanley Miller and Harold Urey demonstrate that organic molecules can be synthesized under prebiotic conditions, and Thomas Cech and Sidney Altman show that RNA can have enzymatic activities.
Stanley Cohen and Herbert Boyer's historic experiment used techniques to cut and paste DNA to create the first custom-made organism containing recombined or "recombinant" DNA.
Stanley Cohen and Herbert Boyer inserted the recombinant DNA molecule they created into E. coli bacteria by means of a plasmid, thereby inducing the uptake and expression of a foreign DNA sequence known as "transformation."
