One gene–one enzyme hypothesis - Wikipedia

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 affects a single step in a metabolic pathway. The concept was proposed by George Beadle and Edward Tatum in an influential 1941 paper on genetic mutations in the mold Neurospora crassa, and subsequently was dubbed the "one gene–one enzyme hypothesis" by their collaborator Norman Horowitz. In 2004… WebThe ‘one gene-one enzyme’ hypothesis has been modified in several different ways. The gene forms a mRNA molecule which serves for coding of protein (enzyme). In some cases several genes form a single mRNA strand, which is then said to be polycistronic.
