    Beadle and Tatum's initial hypothesis, the one gene-one enzyme hypothesis, stated that each gene was responsible for the production of a single enzyme. However, as their research continued, they discovered that some genes produced proteins that were not enzymes, and that some enzymes were composed of multiple protein subunits, each of which was produced by a separate gene.

    In light of these discoveries, Beadle and Tatum revised their hypothesis to the one gene-one primary function hypothesis, which states that each gene is responsible for the production of a single functional protein or RNA molecule, regardless of whether it is an enzyme or not.

    The revised hypothesis allowed for a more accurate understanding of the relationship between genes and proteins, and paved the way for future research in molecular biology. This revision was necessary because it recognized that genes are not only responsible for producing enzymes, but also for a variety of other functional molecules that play important roles in cellular processes.
