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? Selected Answer: 23 and Me • Question 2 3 out of 3 points EPO is a hormone which naturally increases the number of red blood cells in the blood. Selected Answer: Tru e • 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. Selected Answer: Tru e • Question 4 Many of the early set-backs and deaths in the use of gene therapy involved; 3 out of 3 points Selected Answer: An overwhelming immune response to the viral vectors • 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? Selected Answers: The “new” or “healthy” gene must be amplified in number using PCR (polymerase chain reaction) The new gene must be placed into a vector, a piece of DNA which will carry the new gene. The vector DNA is often cut with restriction enzymes which are appropriately called molecular scissors • Question 6 The end result of translation is an amino acid chain which folds into a protein. 3 out of 3 points Selected Answer: Tru e • Question 7 Liposomes can also be used as vectors for gene therapy. They are; 3 out of 3 points Selected Answers: Artificial membranes made of lipids which can enclose the gene and deliver it to the new location in the patient • Question 8 Which of the following is true about EPO? 3 out of 3 points Selected Answers: Was once collected from body fluids of patients Is made by recombinant technology to treat anemia EPO can cause an increase in the number or red blood cells of athletes who train at high altitude • Question 9 PCR is a process to amplify DNA. 3 out of 3 points Selected Answer: Tru e • Question 10 One of the early gene therapy successes involved a genetic based condition 3 out of 3 points called Leber congenital amaurosis which causes blindness. Which of the following are true about this condition? Selected Answers: Although considered rare may affect thousands of children worldwide Hundreds of c
