George W. Beadle's One Gene-One Enzyme Hypothesis …

Beadle, a geneticist, initially worked with the fruit fly Drosophila in the laboratory of Thomas Hunt Morgan at Columbia University. By 1935 he had developed suggestive evidence that eye color, known to be inherited, represents a series of genetically determined chemical reactions. His work over the next six years, much of it with Edward L. Tatum, a biochemist, furthered this hypothesis. But the complexity of Drosophila proved a drawback to developing experiments that would demonstrate a link between specific genes and their chemical products.

The one gene, one enzyme hypothesis is the idea that each gene encodes a single enzyme

what is one- gene one- enzyme hypothesis? | Yahoo …

From Beadle and Tatum's work arose a basic hypothesis: One gene specifies the production of one enzyme. This idea was exceptionally fruitful, but also much debated and eventually modified. Today, it is usually said, more accurately, that each gene specifies the production of a single polypeptide—that is, a protein or protein component. Thus, two or more genes may contribute to the synthesis of a particular enzyme. In addition, some products of genes are not enzymes per se, but structural proteins.

The "One Gene- One Enzyme" Hypothesis (November …

In his Nobel lecture, given shortly after he joined the Rockefeller Institute, Tatum outlined the concepts, fundamental to genetics, underlying the one-gene, one-enzyme (understood today as one-gene, one-polypeptide) hypothesis: all biochemical processes in all organisms are under genetic control; these overall biochemical processes are resolvable into a series of individual stepwise reactions; each single reaction is controlled in a primary fashion by a single gene, or in other terms, in every case a 1:1 correspondence of gene and biochemical reaction exists, such that mutation of a single gene results only in an alteration in the ability of the cell to carry out a single primary chemical reaction.
