Question
which of the following regarding DNA is incorrect? Please answer the entire page!!! 58. DNA sequencing by termination uses dideoxyribonucleotides because: A. DNA polymerase chain them will not utilize B. they work more at high temperatures C. they cannot be incorporated into DNA strand D. because once into the growing DNA strand, they prevent the incorporation subsequent incorporated nucleotides 59. Origins of replication occur: A. in multiple copies and in tandem B. in multiple copies interspersed throughout the genome C. as single copy DNA. D. at the telomeres E. at the centromeres 60. In the Hershey-Chase experiment, the majority of A P-radiolabeled DNA was found in the supernatant (outside bacterial cells) B."P-radiolabeled protein was found in the supernatant (outside bacterial cells) c. uss-radiolabeled DNA was found in the supernatant (outside bacterial cells) D. ss-radiolabeled protein was found in the supernatant (outside bacterial cells) 61. If a fragment of DNA is 2000 base pairs in length, the fragment contains nucleotides A. 1000 B. 2000 C. 4000 D. 20,000 62, Select the correct statement: A. Core histones H2A, H2B, H3 and H4 assemble to form a tetramer (4-subunit complex). B. Charged amino acids are responsible for the binding of DNA around core histones. C. Nucleosome-level compaction of DNA accounts for a 50-fold shortening of the DNA fiber. D. Core histone complexes comprised of H1, H2A H2B and H3 occur approximately every 200 along the DNA 63. Which of the following statements regarding the lagging strand is INCORRECT. A. Synthesis is discontinuous B. Only one RNA primer is present C. The segments of DNA are called Okazaki fragments D. DNA is synthesized in the 5'-3' direction 64. Which of the following does not contribute to DNA fidelity? A. Proofreading B. Stability of base pairing C. Structure of DNA polymerase active siteExplanation / Answer
