CHAPTER 17 AP BIOLOGY MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) Beadle & Tatum proposed the one gene-one enzyme concept. In its original form, this hypothesis could now be restated in which of the following ways? A) One DNA molecule contains the information to make one enzyme. B) Each polypeptide is the result of the activity of one enzyme. C) Each gene contains the information to make one enzyme, one lipid, & one carbohydrate. D) A given sequence of DNA nucleotides contains the information to make one enzyme. E) Each gene is actually an enzyme that catalyzes the production of one protein. The following questions refer to the following simple metabolic pathway: 2) According to Beadle & Tatum's one gene-one enzyme hypothesis, how many gene(s) is (are) necessary for this pathway? A) 3 B) 1 C) 0 D) 2 E) It cannot be determined from the pathway. 3) A mutation results in a defective enzyme a . Which of the following would be a consequence of that mutation? A) an accumulation of A & no production of B & C B) an accumulation of C & no production of A & B C) an accumulation of B & no production of A & C D) an accumulation of A & B & no production of C E) an accumulation of B & C & no production of A 4) One strain of a diploid organism is homozygous for a recessive allele coding for a defective enzyme a . Another strain is homozygous for a recessive allele coding for a defective enzyme b . Crossing those two strains will result in a strain that would grow on which of the following? A) a minimal medium supplemented with both A & B B) a minimal medium supplemented with A C) a minimal medium supplemented with B D) All of the above will support the growth of the new strain. 5) Which of the following represents a similarity between RNA & DNA? A) the presence of an OH group on the 3' carbon of the sugar B) the presence of a double-stranded helix C) nucleotides consisting of a phosphate, sugar, & nitrogen base D) repair systems that correct genetic code errors E) the presence of uracil 6) The nitrogenous base adenine is found in all members of which of the following groups?
