FALL 2017 BIOLOGY 3 FINAL EXAM A 31 Who was the research team that determined the structure of the DNA molecule? A. Griffith and Hammerling c. B. Hershey and Chase D. Watson and Crick E. Gregor Mendel 82. A region of DNA that either specifies a particulat protein or that helps to regulate another region is called a 33. When DNA duplicates itself the process is known as: 34. When a polypeptide is formed at the ribosomes, using information encoded in RNA, it is referred to as 35. Which of these sequences most accurately describes the pattern involved in the synthesis of a protein: A. gamete B. zygote C. genotype D. gene A. template duplication B. DNA transcription C.replication D. DNA synthesis E. retrotranscription A. translation B. transcriptionC. polypeptide transfer D. amino acid transferE. replication B. DNA-*IRNA-+ mRNA-protein D. DNA+ mRNA-+protein A. DNA tRNA-xprotein E) mRNA DNA-xprotein The ultimate source of all new alleles is: A evolution B. mutation C. natural selection D. non-random mating 36. E. genetic drift 37. The most widely accepted mechanism that contributes to the evolutionary process is: B. natural selection C.community selection E. neutral selection D. homeostatic mechanisms Who are the two biologists that suggested plausible explanations for the mechanism of evolution? A. Darwin and Koch C. Darwin and Wallace B. Darwin and Pasteur E. Watson and Crick D. Darwin and Darwin selection is contingent upon: C. heterotrophs genetic diversity D. poorly adapted organisms B. autotrophs E. exons and introns 40. Evolution is defined as A. genetic changes that occur within the lifetime of an organism B. changes in the appearance of an organism C. changes in the environment and climatic condition of the earth D. changes in allele frequencies in a population of organisms that occur over time E. phenotypic changes due to genetic drift 41. All experiments that simulate conditions in the early earth's atmosphere assume that the early atmosphere did NOT contain which gas? A. water vapor B. methane C. oxygen D. hydrogen E carbon dioxide The first self-replicating molecules were A. DNA 42. C. ribozymes D. enzymes E cells B. RNA that 43. The longer two species have been evolving on their own, the greater the number of, accumulate between them A. genetic differences C. genetic similarities B.DNA bases What is the name given to the process by which a larva develops into an adult? A. gastrulation 44. p. D nerulation B. metabolic mechanisms for maintaining a constant body temperature, as A. endothermic is to homeothermic C. ectothermic is to endothermic 45.
