As Beadle and Tatum had predicted, they were able to create single gene mutations that incapacitated specific enzymes, so that the molds with these mutations required an external supply of the substance that the enzyme normally produced, and the substance that the enzyme normally used, piled up in the cell. These results led them to the one gene/one enzyme hypothesis, which states that each gene is responsible for directing the building of a single, specific enzyme.
Beadle and Tatum's experiment with Neurospora demonstrated that mutations in specific genes caused defects in specific enzymes. This supported their "one gene-one enzyme" hypothesis, as each gene encoded a specific enzyme in a biochemical pathway. By identifying mutants that could not grow on certain media, they were able to link specific gene mutations to specific enzyme deficiencies.

What was the hypothesis that George Beadle formulated while studying eye color mutations in Drosophila?
George Beadle formulated the hypothesis that each gene is responsible for controlling the production of a single enzyme in the biochemical pathway. This became known as the "one gene-one enzyme hypothesis" and laid the foundation for understanding the relationship between genes and proteins.
Beadle and tatum's hypothesis?
Beadle and Tatum proposed the one gene-one enzyme hypothesis, suggesting that each gene is responsible for producing a specific enzyme. They conducted experiments with Neurospora crassa, a bread mold, to demonstrate the relationship between genes and enzymes in the process of biochemical pathways. Their work laid the foundation for understanding the relationship between genes and proteins.
How did beadle and tatum's research result in the one gene-one polypeptide hypothesis?
The major breakthrough in demonstrating the relationship between genes and proteins came in the 1940s. American geneticists George Beadle and Edward Tatum worked with the orange bread mold Neurospora crassa. Beadle and Tatum studied mutant strains of the mold that were unable to grow on the usual nutrient medium. Each of these mutant strains turned out to lack a single enzyme needed to produce some molecule the mold needed, such as a vitamin or an amino acid. Beadle and Tatum also showed that each mutant was defective in a single gene. Their research led them to propose the "one gene-one enzyme" hypothesis. This hypothesis states that the function of an individual gene is to dictate the production of a specific enzyme.Since then, scientists have learned that some genes actually dictate the production of a single polypeptide, which may make up part of an enzyme or another kind of protein. Beadle and Tatum's hypothesis is now generally stated as one gene-one polypeptide.
Beadle an Tatums experiment provide a chemical explanation for dominace and recessiveness?
Beadle and Tatum's experiment showed that genes control the production of specific enzymes in biochemical pathways. In terms of dominance and recessiveness, this means that dominant alleles produce functional enzymes that mask the effects of recessive alleles that produce nonfunctional enzymes. This can lead to varying degrees of enzyme activity and ultimately determine the observable traits in an organism.
What did Beadle and Tatum conclude from their studies with the red bread mold Neurospora crassa?
Beadle and Tatum concluded that genes control the synthesis of enzymes, proposing the "one gene-one enzyme" hypothesis. This research laid the foundation for the understanding of how genes encode proteins and paved the way for the field of molecular genetics.
One gen one enzyme hypothesis was proposed by?
The "one gene, one enzyme" hypothesis was proposed by George Beadle and Edward Tatum in 1941. They suggested that each gene is responsible for encoding a specific enzyme involved in biochemical pathways. This hypothesis laid the foundation for our understanding of how genes control various metabolic processes in cells.
