The beadle and tatum experiments were based on all of the following assumptions except that x-irradiation can induce mutations. supplemented media permit growth of auxotrophic strains of neurospora two strains of auxotrophic neurospora that grow on minimal medium supplemented with biotin have mutations in the same gene auxotrophs fail to grow on minimal media

The correct answer to the question: The Beadle and Tatum experiments were based on all of the following assumptions, except that:___, would be: Two strains of auxotrophic Neurospora grow on minimal medium supplemented with biotin have mutations in the same gene.

Explanation:

The experiment that was carried out and presented by George W. Beadle and Edward L. Tatum, in 1941, shed a lot of light not only on how enzymes and other proteins and chemical reactions function, but also the role that genes play in these processes, especially when there is presence, or absence of certain conditions. The experiment was titled: "Genetic Control of Biochemical Reactions in Neurospora" and it worked particularly with samples of the bread mold known as Neurospora. It is called auxotrophic because this type of mold was found to be incapable of producing certain compounds that were required for its proper functioning and development. The only principle on which this particular experiment was not based on ws the assumption the one on the second to last answer option. All the other options were part of the assumptions that these researchers had.

b is the correct answer
