Many aspects of gene function can be nicely explained with the one-gene-one-enzyme hypothesis, which states that a gene controls the production of an enzyme. Which of the following findings about gene expression, though, requires an expansion of this simple concept? Choose an answer below: Non-enzyme proteins are made from genes too. Some genes code for RNA molecules only. Enzymes composed of different polypeptides are coded for by more than one gene. a and c, but not b a, b, and c

A researcher examines genes for several proteins that are quite similar in both structure and function. He is interested in determining whether the genes form a multigene family and in working out which of the proteins arose first evolutionarily. What would be the BEST approach to take to address this question? Be careful to look for the best approach; some other approaches could also provide useful information while being less definitive. A. The researcher should sequence the genes and compare their sequences. The most similar genes are likely the most closely related, while those that have more base differences probably diverged earlier. B. The researcher should examine the functions of the proteins. Those with the most similar functions are the most closely related. C. The researcher should induce mutations in the genes to see how these affect the function. The most mutations needed to cause changes in the function of the protein, the older the gene. D. The researcher should…
