Beadle and Tatum conducted experiments using the mold Neurospora crassa, exposing it to X-rays to induce mutations. They then analyzed the growth of these mutant strains on minimal media supplemented with specific nutrients. By observing which nutrients were required for the growth of each mutant, they inferred which biochemical pathways had been disrupted, leading to their conclusion that each gene is responsible for a specific enzyme in a metabolic pathway. This foundational work established the one gene-one enzyme hypothesis.
George Beadle and Edward Tatum won the Nobel Prize in Physiology or Medicine in 1958 for their discovery of the role of genes in regulating biochemical processes within cells.
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.
The theory you are referring to is the "one gene-one enzyme" hypothesis proposed by Beadle and Tatum in the 1940s. This theory suggested that each gene is responsible for encoding a specific enzyme, which catalyzes a specific biochemical reaction in an organism. Although it has been modified over time, the concept remains fundamental to our understanding of how genes encode proteins and their functions in cells.
They used Neurospora Crassa (a bread mold). It could grow in a simple medium which helped aid in their research.
Frederick Griffith's experiments with pneumococcus bacteria did not directly contribute to the conclusion that all eukaryotic cells contain a full complement of genetic information. Instead, the experiments performed by George Beadle and Edward Tatum with Neurospora crassa in the 1940s provided the first definitive evidence for the one gene-one enzyme hypothesis and demonstrated that mutations in genes can disrupt specific metabolic pathways.
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.

Beadle and Tatum used bread mold (Neurospora crassa) to demonstrate that each gene is responsible for encoding a specific enzyme in a biochemical pathway. By creating mutants that were unable to produce certain enzymes, they showed how mutations in specific genes can disrupt metabolic pathways. This work laid the foundation for the "one gene, one enzyme" hypothesis.
beadles and tatums hypothesis was that mutations occured when one gene made two poteins it was evidential that beadles and tatums hypothesis had altered in 1941 when tatum found a mutation in one of there experiments.
