Page 1 The following is an exam given in 2006; it is intended to be an example of the type & style of questions given on an exam. Using this as your primary study material for the Spring 2009 exam 1 would be a mistake. BIOL 1362 Exam 1 from Spring 2006 CH 11 1. The Hershey–Chase experiment determined that A) protein and DNA are the hereditary materials of viruses. B) protein, not DNA, is the hereditary material of viruses. C) viruses do not contain hereditary material. D) DNA, not protein, is the hereditary material of viruses. E) None of the above Ans: D 2. The antiparallel relationship of the two strands of DNA refers to the A) twisted configuration of the strands. B) alternative branching pattern of the strands. C) alignment of the strands, such that one strand starts with a 3 carbon linked to a hydroxyl (-OH) group, the other with a 5 carbon linked to a phosphate group. D) view at one end of the molecule–one strand has an A wherever the other has a T, and one has a G wherever the other has a C. E) All of the above Ans: C 3. What is the main reason why RNA is incorporated into the DNA molecule during DNA replication? A) RNA primase adds bases that act as primers. B) RNA primase is able to use DNA as a template. C) RNA primase must be incorporated into the replication complex. D) DNA polymerase can only add on deoxyribonucleotides to an existing primer strand. Ans: D 4. Semiconservative replication of DNA involves A) each of the parental strands acting as a template for a new strand, leading to the formation of 2 DNA double helical molecules, each comprised of a parental & daughter strand. B) only one of the parental strands acting as a template for a new strand. C) the complete separation of the parental strands, the synthesis of new strands, and the reassembly of the parental strands. D) formation of a hybrid mixture of parental and daughter DNA. E) None of the above Ans: A 5. In DNA replication, each newly made strand is A) identical in DNA sequence to the strand from which it was copied. B) complementary in sequence to the strand from which it was copied. C) oriented in the same 3 to 5 direction as the strand from which it was copied. D) an incomplete copy of one of the parental strands. E) a hybrid molecule consisting of both ribo- and deoxyribonucleotides. Ans: B

Page 2 Use the following to answer questions 6-7: The figure below shows a replication bubble that forms in the process of the replication of eukaryotic DNA. A, B, C, and D indicate newly synthesized DNA strands; "E" indicates a region rather than a particular structure; G and H are pointing to the ends of strand "C". 5’ 5’ 3’ 3’ A C D B E F E G H 6. The region of this replication bubble represented by “E” is called the ________. The enzyme responsible for linking together DNA fragments at the end of replication (not shown in the diagram) is called ____________. A)
