Chapter 1, Problem 1TC

Biotechnology is the manipulation of living organisms and organic material to serve human needs. Which is not an example of biotechnology? A. Yeast in bread making and alcohol production   B.Use of beneficial bacteria (penicillin) to kill harmful organisms C.Cloning of plants and animals                                                             D. Coal fired power plants

Gene therapy (or cell therapy) is the name of a newer type of cancer treatment. Describe an example of how it works, and why it is different from conventional treatments.

In 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a persons own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwangs group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?

Cancer can arise spontaneously, but it can also be induced as a result of environmental factors such as sun exposure, infections, and tobacco smoking. If you were asked to help allocate resources to cancer research, what emphasis would you place on research to find cancer cures, compared to that placed on education about cancer prevention?

In not less than 200 words. Discuss why scientist is excited about human embryonic and adult stem cell.

Stem cells: Describe some of the ways that this scientist relied on previous disciveries and techniques to make his breakthrough.

Bishop and Varmus’s experiment was a landmark work in cancer biology. What was the question facing the scientists about src gene? Explain the experiment and how the results solved their question.

Which best describes genetic mutations? A) Genetic mutations that cause diseases are always passed on to offspring. B) Some inherited genetic mutations can be good for the offspring. C) Different genetic mutations cause few forms of cancer. D) Somatic mutations can be inherited from parents or acquired during life.
