SCIENCE, TECHNOLOGY, AND SOCIETY Imagine that you are a genetic counselor. What advice or suggestions might you give in the following situations? (a) A couple has come for advice because the woman had a sister who died of Tay-Sachs disease. (b) A young man and woman who are not related are engaged to be married. However, they have learned that the mans parents are first cousins, and they are worried about the possibility of increased risk of genetic defects in their own children. (c) A young womans paternal uncle (her fathers brother) has hemophilia A. Her father is free of the disease, and there has never been a case of hemophilia A in her mothers family. Should she be concerned about the possibility of hemophilia A in her own children? (d) A 20-year-old man is seeking counseling because his father was recently diagnosed with Huntingtons disease. (e) A 45-year-old woman has just been diagnosed with Huntingtons disease. She says she will not tell her college-age sons because of the burden it will place on them. Given that the woman, not her sons, is your client, do you have a duty to inform the sons? Explain your reasoning.
1. How may recombinant DNA molecules be introduced into human cells? a. by splicing the needed genes into a mammalian chromosome using restriction enzymes. b. by adding plasmids to the mammalian cells. c. by using engineered viruses as vectors. d. by using a gene gun. 2. If someone is accused of a crime, investigators can collect his or her DNA to compare the DNA of the cells found at the crime scene. To collect human DNA, investigators often swab the inside of person’s cheek. Just a few human cheek cells contain enough material to perform PCR. In a cell, the nucleus and mitochondria contain DNA that is the starting material for PCR. Identify the 4 components needed to start a PCR reaction (equipment not included)
7. Why recombinant DNA is very useful in improving our health conditions?A. Human insulin can be reproduced by bacteria?B. Vaccine can be reproduced by fungi or bacteriaC. Human growth hormone can be obtained from E. ColiD. All of the above 8. Which of the following is/are example of genetic engineering?A. A farmer choose a breed of cow for greater milk production.B. The use of bacteria in order to produce human insulinC. The insertion of clone genes to plant cellsD. Cross pollination of squash flowers. 9. Bacterial cells as host organisms may expose the gene to make protein products such as insulin and growth hormone . Which of the following processes are involved?A. replication and transcription. B. Transcription and replication C. Transcription and transformation. D. Replication and transformation

1. If you create your own species using recombinant genetics, what organism would you can create?
1) What do you want to learn, if anything, about your own genome? Answer: Honestly i am not a biological son of my parents therefore i am an adopted child, so what comes in my mind of knowing my own genome is to know about Genetic and biochemical disorder of my real parents or ancestors if there is any. Is my answer correct? if not, please make it correct
9. What is the unit of a genetic map? A. centimorgan B. angstrom C. joule D. centimeter
4. It is known that RNA is a nucleic acid responsible for the synthesis of proteins. However, there is another nucleic acid alongside RNA: DNA. What role does the latter play in relation to RNA? a) RNA is synthesized in the cell in case too large a mutation damages the DNA. b) DNA has the reproductive genetic code of all cells and passes it on to RNA. c) DNA directs the synthesis of enzymes, while RNA synthesizes proteins. d) DNA synthesizes RNA according to a blueprint that includes the guidelines necessary for the structure of proteins.
