One gene, one enzyme hypothesis is given by Beadle and Tautum.
With more understanding on genes, now we know that all genes do not code enzymes only. There are some proteins which do not function as enzymes. There are enzymes having many subunits and each coded by a different sub unit.
Alternate splicing,overlapping genes etc , all of them accept the fact that the genes have lot more other functions than just code enzymes. But all proteins are coded by genes only. Now-a-days the hypothesis is called more correctly as one gene, one polypeptide hypothesis.
So the only statement which does not support the concept is options 'a'. Some enzymes are not coded by genes.
All enzymes are coded by genes only. But genes do more than just coding enzymes.

QUESTION 1 George Beadle and Edward Tatum performed an experiment in which they made single-gene mutations in the bread mold Neurospora crassa. These mutations resulted in several Neurospora auxotrophs. Further analysis revealed specifically how the mutations affected synthesis of the amino acid in question. What was the significance of these results? A single gene encodes a single protein, in the case of this experiment, an enzyme. Enzymes are needed to synthesize amino acids. They showed that mutations are heritable. They...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
