ETHC 210 Exam 7 - Questions and Answers ETHC 210 EXAM 7 (75 OUT OF 75) 1. In 2013 what genetics testing company came under scrutiny for allegedly incorporating eugenic ideals by promoting the idea of prescreening their egg and sperm donor DNA for genetic defects so customers could avoid those samples? 2. EPO is a hormone which naturally increases the number of red blood cells in the blood. 3. Microarray’s are used by DNA sequencing companies like 23 and Me to provide the customer with information about a predetermined set of genes or DNA sequences which they may possess because they bind to corresponding genes on the microarray. 4. Many of the early set-backs and deaths in the use of gene therapy involved; 5. To prepare genes which will be inserted into a patient for gene therapy which of the following steps must be done using current technology? 6. The end result of translation is an amino acid chain which folds into a protein. 7. Liposomes can also be used as vectors for gene therapy. They are; 8. Which of the following is true about EPO? 9. PCR is a process to amplify DNA. 10. One of the early gene therapy successes involved a genetic based condition called Leber congenital amaurosis which causes blindness. Which of the following are true about this condition? 11. Pigs cannot extract phosphorus from cereal so phosphorus is put into their diets. However this leads to excess phosphorus in their manure. This is a problem because; 12. PCR involves a heat resistant DNA polymerase which copies DNA into many copies. 13. Most gene therapy vectors under current use are disarmed viruses. 14. Olympic athletes are now tested for EPO in their urine but recombinant EPO and natural EPO cannot be distinguished by the test. 15. Which of the following is true regarding microarray structure, function and their use to relay genetic information. 16. Which of the following living organisms have a GMO counterpart? 17. Gene therapy is a technique which involves; 18. GMO salmon are salmon which have been genetically altered to grow faster and are grown in special aquatic enclosures to prevent them from getting in natural waterways. What are some problems which could arise from this technology? 19. Recombinant DNA; 20. Genetics counseling can involve pedigree construction of family inheritance. 21.

Recombinant DNA technology has been used to make insulin. Insulin operates by; 24. A transgenic organism can be an organism which contains human genes to make human proteins which can be extracted for drug use for patients. 25. Gene silencing involves antisense molecules, ribozymes and RNA interference to block translation of mRNAs.
