Question

41. You are a forensic anthropologist. You uncover a bone fragment that dates back to the Pleistocene era You wonder, could this be a new species of Hominid? The DNA is in bad shape, but you figure out that the G-C content was 64% of the genome. Known hominids from that era had an A-T content of 36%. Chargaff's rules, is this a new species of hominid? Applying Aj Yes [B] No 42. What are "germs" a. Microorganisms that cause disease b. viruses that cause disease c. bacteria that cause disease d. None of the above e. All of the above 43. Which is NOT true about Malaria a. It is caused by a protozoan (Kingdom: Protista) transmitted by mosquitos b. Millions of people die of Malaria each year c. There is no effective vaccine. d. Genetic modification of mosquitos might be a way to end its spread 44. Which of the following is NOT true about gene expression in Eukaryotes? a. Gene expression can be regulated in the nucleus epigenetically. b. Gene expression can be regulated transcriptionally by RNA editing Gene expression can be regulated in the cytoplasm by translation. c. d. Gene expression can be regulated in the nucleus by post-translational modifications e. None of the above (all of the above statements are TRUE) Match the term or statement with the correct type of cloning A) Molecular B) Reproductive C) Therapeutic 45. Recombinant DNA is also known as A cloning 46. Genetically Modified Organisms (GMOs) are examples of A cloning 47. The use of stem cells to treat arthritis is an example of_ cloning 48. Dolly the sheep is a celebrity example of cloning 49. A transgenic animal is produced by which type of cloning? A 50. Which is not a step necessary to clone your beloved pet, Fifi a. Acquire a somatic cell from Fif b. Acquire a germ cell (sperm or ova) from Fif C Acquire a ovum (egg cell) from the same species as Fif Transfer the genetic material from Fifi into an enucleated ovum of the above (all are necessary steps for the cloning of Fifi)

Explanation / Answer

41. True

Chargaff's rule: Purines = Pyrimidines

GC = 64%

AT = 36%

Total = 100%

42. Option E is correct.

Germs = Microorganisms (Bacteria, virus, protozoans, and fungi) that cause disease.

43. Option D is correct.

Malaria is caused by Plasmodium. Over a million people die of malaria every year. There is no effective vaccine to malaria.

44. Option D is correct.

Post-translational modifications occur in the cytoplasm.

45. Molecular cloning

46. Molecular cloning

47. Therapeutic cloning

48. Reproductive cloning

49. Molecular cloning
