Ken,
Prior to the 1940s, most biologists beleived that proteins were the 
genetic material of cells, based on the reasoning that molecules made of 
20 different building blocks (amino acids) would be able to encode more 
complex information than a molecule made up of only 4 building blocks 
(nucleotides).  Until this misconception was proved wrong by Hershey and 
Chase at the Cold Spring Harbor labs, there was no hope of figuring out 
the basis of heredity, since people were looking at the wrong molecues.
