Textbook Question
Chapter 4, Problem 17BS
Scientists can manipulate living cells, changing their genetic composition and the way they function. Some companies have sought to patent engineered cell lines. Should society allow cells to be patented? Should the same patent rules apply to human and bacterial cells?

- 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?arrow_forwardGather recent and related research articles about cell. Make use of various sources journals, magazines, and internet. Make summary of each article. Then put together and synthesize the information found in the different researches you gathered. FRom your synthesis, justify how the study of the cells can help improve the lives of many organisms, e.g promotion of proper nutrition and healthful habits.arrow_forwardWhy do you think few scientist works on nanotechnology?arrow_forward
- Which of the following best describes an observation/experiment from a model organism that has advanced our understanding of cell biology? Select one: a. Radiation caused the denaturation of actin proteins in yeast. b. The risk of cancer increases as humans age. c. COVID is pathogenic due to the shape of specific of interacting proteins d. Fruit flies have wings that help them fly. e. Hemoglobin is found in mice as well as rats and pigeons.arrow_forwardStem cells: How do you think stem cells could be used to treat diseases?arrow_forwardSuppose you find a sample of cells at a crime scene.

- You can choose one or more than one option: The cytosol: is a static liquid inside the nucleus contains RNA supports the cell and determines its shape contains water as the major quantitative component chemically modifies proteins and other moleculesarrow_forwardThe drug taxol is extracted from the bark of yew trees. It binds tightly to microtubules and stabilizes them. When added to cells, it causes much of the free tubulin to assemble into microtubules. Taxol can be used as an anticancer drug. At the molecular level, what does the drug prevent? At the cellular level, what part of cell division does it prevent? Be specific.arrow_forwardWhen we have a bacterial infection, we often take antibiotics. Why do antibiotics only kill bacterial cells and not our own human cells? They do kill human cells but there are far more human cells than bacterial cells and they will quickly repopulate after the infection. Antibiotics are proteins that can only bind to bacterial cell wall receptors. Antibiotics target structures of bacterial cells that human don't have, such as a nucleus. Antibiotics target structures of bacterial cells that human don't have, such as peptidoglycan. 0000arrow_forward
- You are looking at the inside of a cell . How can you tell the cell is animal, bacterial or a plant cell ?Single choice. A. animal cell - nucleus ,no cell wall; bacteria cell -no nucleus ; plant cell- nucleus, cell wall and chloroplast B. animal cell - no nucleus, no cell wall ; plant cell - nucleus , no cell wall C. bacteria cell- nucleus ,no cell wall ; animal cell - nucleus ,cell wallarrow_forward_17. Which of the following is the correct sequence of events for the development of cell theory? A) Manufacturing and using simple microscopesdetermining that all living organisms are comprised of cells determining that plants are comprised of cells understanding that new cells are produced by preexisting cells B) Manufacturing and using simple microscopes → determining that plants are comprised of cells determining that all living organisms are comprised of cells → understanding that new cells are produced by preexisting cells C) Determining that plants are comprised of cells determining that all living organisms are comprised of cellsmanufacturing and using simple microscopes understanding that new cells are produced by preexisting cells D) Manufacturing and using simple microscopes understanding that new cells are produced by preexisting cells determining that plants are comprised of cells determining that all living organisms are comprised of cells ->arrow_forwardBus #2: You head into a stem cell. Ms. Frizzle points out that there is a drug in this cell that appears to interfere with mitosis. In other words, it takes longer than usual for the cell to finish mitosis. She says, "this drug could be doing any number of things. Propose one GOOD working hypothesis, a GOOD null hypothesis, and a WELL-DESIGNED experiment to test your working hypothesis."arrow_forward
