Established the chromosomal theory of inheritance.

Showed that Fred Grffiths "transforming principle" was DNA.
-
Isolated DNA from different organisms and measured the levels of each of the four nitrogenous bases.
-
Produced X-ray crystallography pictures of BDNA which Watson and Crick use to determine the structure of double-standard DNA.
-
Proved phage DNA, and not protein was the genetic material
-
Solved the structure of DNA
-
Solved the structure of DNA. Also, reasoned that the sequence of nucleotides in the molecule must function as a code. He called this Central Dogma.
-
Made a cell free system that replicates DNA.
-
Showed that rRNA was not the template for building proteins.
