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 tigure out that the -c content was 64% of the genome. Known hominids from that era had an A-T content of 36%. Applying Chargaff's rules, is this a new species of hominid? 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. c. Gene expression can be regulated in the cytoplasm by translation 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) ) Molecular B) Reproductive C) Therapeutic 45. Recombinant DNA is also known asc 46. Genetically Modified Organisms (GMOs) are examples ofcloning. 47. The use of stem cells to treat arthritis is an example ofcloning. 48. Dolly the sheep is a celebrity example of cloning. 49. A transgenic animal is produced by which type of cloning? cloning. Vhich is not a step necessary to clone your beloved pet, Fifi? Acquire a somatic cell from Fifi Acquire a germ cell (sperm or ova) from Fifi Acquire a ovum (egg cell) from the same species as Fifi Transfer the genetic material from Fifi into an enucleated ovum None of the above (all are necessary steps for the cloning of Fifi)

Explanation / Answer

Ans-41 No because the known hominids and the newly discovered have similar G-C content 64% and similar A-T content 36% .

Ans-42 the correct option is (E) i.e all of above because all the microorganisms like virus, bacteria, fungi and micro parasite which causes disease are germs.

Ans-43 option (B) is not true about malaria i.e. millions of people die because of malaria.

Ans-44 option (B) is not correct i.e. gene expression can be regulated by the transcriptionally RNA editing because it only cause deletion or substitution of nucleotide.
