Beadle and Tatum's 1941 Breakthrough ... Beadle and Tatum set out to provide experimental proof of the connection between genes and enzymes. They hypothesized that if there really was a one-to-one relationship between genes and specific enzymes, it should be possible to create genetic mutants that are unable to carry...

One gene-one enzyme hypothesis - Wikipedia, the free encyclopedia
The one gene-one enzyme hypothesis is the idea that genes act through the production of enzymes, with each gene responsible for producing a single enzyme that in turn effects a single step in a meta...

In 1941, Beadle and Tatum turned to a simpler creature, in which specific products of metabolism could be directly studied. A bread mold, Neurospora crassa, proved ideal. Neurospora can be cultured together with sugar, inorganic salts, and the vitamin biotin.

Behind every major scientific effort is a story. ... Beadle and Tatum's story is one of persistence. They began with a hypothesis: each gene causes the production of a single enzyme, and that enzyme catalyzes a biochemical reaction within an organism.

Beadle and Tatum proposed the "one gene one enzyme" theory. One gene codes for the production of one protein. "One gene one enzyme" has since been modified to "one gene one polypeptide" since many proteins (such as hemoglobin) are made of more than one polypeptide...

Beadle and Tatum's principal difficulty was that in the 1940s we knew relatively little about the chemical nature of genetic material. The prevailing view then was that genetic material might be protein. Existing information on DNA structure suggested that it consisted of repetitive nucleotide sequences.
