Why has beadle and tatoms one gene - one enzyme hypothesis been midified since the presented it in 1940s?

Tatum and Beadle proposed the "one gene one enzyme" theory. One gene code is responsible for the production of a single protein. "One gene one enzyme" is modified to "one gene one polypeptide" because the majority of proteins are composed of multiple polypeptides.

How did the results of Beadle and Tatum's experiment support their hypothesis?
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.
What was the hypothesis that George Beadle formulated while studying eye color mutations in Drosophila?
He formulated that an enzyme that catalyses eye color was being prevented.
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.

Who won the 1958 nobel prize one gene one enzyme?
In 1958, George Wells Beadle and Edward Lawrie Tatum won the Nobel Prize in Physiology or Medicine for their work on the one gene-one enzyme hypothesis. They also shared the prize with Joshua Lederberg, for his achievement of discovering that bacteria mate and exchange genes.
What did Beadle and Tatum conclude with the red bread mold?
One gene controls the synthesis of one enzyme.
What did Beadle and Tatum conclude from their studies with the red bread mold Neurospora crassa?
one gene controls the synthesis of one enzyme
What is the name of the theory that describes how an enzyme works?
Lock and Key hypothesis
The lock and key hypothesis attempts to explain the mechanism of?
enzyme specificity
Who was George Beadle partner?
His partner's name was Edward Lawrie Tatum and together they developed the "one gene, one enzyme theory." The theory, all summarized, stated that each gene controls a particular enzyme.
What simple experiment might you perform to test the hypothesis that an enzyme combines with its substrate when it acts?
in the absences of the enzyme the reaction is very slow,and at the end of the reaction enzyme is separated that shows substrate 1st bind to the enzyme
