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...
2.5 pts D Question 27 Which of the following statements is FALSE? o In Archaea there is only one turn of DNA around a nucleosome comprised of the histone H3-H4 tetramer Modifications of histone H3 tails at the K9 position can result in either repression or gene activation, depending of the type of modification. O There are 4 copies of each histone, including H1, in the eukaryotic nucleosome. Archaea have no histone tails since there are no higher orders of...
