ETHC 210 EXAM 7 (100% CORRECT) | SCORE 75 OUT OF 75 POINTS : LIBERTY UNIVERSITY

ETHC 210 EXAM 7 • Question 1 3 out of 3 points 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? • Question 2 3 out of 3 points EPO is a hormone which naturally increases the number of red blood cells in the blood. • Question 3 3 out of 3 points 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. • Question 4 3 out of 3 points Many of the early set-backs and deaths in the use of gene therapy involved; • Question 5 3 out of 3 points To prepare genes which will be inserted into a patient for gene therapy which of the following steps must be done using current technology? • Question 6 3 out of 3 points The end result of translation is an amino acid chain which folds into a protein. • Question 7 3 out of 3 points Liposomes can also be used as vectors for gene therapy. They are; • Question 8 3 out of 3 points Which of the following is true about EPO? • Question 9 3 out of 3 points PCR is a process to amplify DNA. • Question 10 3 out of 3 points 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? • Question 11 3 out of 3 points 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; • Question 12 3 out of 3 points PCR involves a heat resistant DNA polymerase which copies DNA into many copies. • Question 13 3 out of 3 points Most gene therapy vectors under current use are disarmed viruses. • Question 14 3 out of 3 points Olympic athletes are now tested for EPO in their urine but recombinant EPO and natural EPO cannot be distinguished by the test. • Question 15 3 out of 3 points Which of the following is true regarding microarray structure, function and their use to relay genetic information. • Question 16 3 out of 3 points Which of the following living organisms have a GMO counterpart? • Question 17 3 out of 3 points Gene therapy is a technique which involves; • Question 18 3 out of 3 points 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? • Question 19 3 out of 3 points Recombinant DNA; • Question 20 3 out of 3 points Genetics counseling can involve pedigree construction of family inheritance. • Question 21 3 out of 3 points DNA analysis and genetics testing can be done after death. • Question 22 3 out of 3 points Which of the following is true about restriction enzymes, molecular scissors which make gene therapy possible? • Question 23 3 out of 3 points Recombinant DNA technology has been used to make insulin. Insulin operates by; • Question 24 3 out of 3 points A transgenic organism can be an organism which contains human genes to make human proteins which can be extracted for drug use for patients. • Question 25 3 out of 3 points Gene silencing involves antisense molecules, ribozymes and RNA interference to block translation of mRNAs.
