Textbook Question
Chapter 18, Problem 14TYU
SCIENCE. TECHNOLOGY, AND SOCIETY Trace amounts of dioxin were prsent in Agent Orange, a defoliant sprayed on Vegetation during the Vietnam War. Animal tests suggest that dioxin can cause birth defects, cancer, liver and thymus damage, and immune system suppression, sometimes leading to death. but the animal tests are equivocal; a hamster is not affected by a dose that can kill a guinea pig. Dioxin acts like a Steroid hormone, entering a cell and binding to a cytoplasmic receptor that then blnds the cell's DNA.
- (a) Discuss how this mechanism might help explain the vari- ety of dioxin's effects on different body systems and in different animals.
- (b) Discuss how you might determine whether a type of illness is related to dioxin exposure. Next, discuss how you might determine whether a particular individual became ill as a result of exposure to dioxin. Which would be more difficult to demonstrate? Why?

- Select all that apply: The aim of the fentanyl project in Baker's group is to do the following to detect the biohazard: | a. Grow the genetically engineered organisms in areas where the biohazard may be deployed. | b. Generate a customized protein that is modified to glow when fentanyl binds to the receptor site. | c. Genetically engineer thale cress to produce customized proteins that they have designed. | d. Custom engineer proteins that glow with fentanyl for use in a spray that can be applied in the field. O e. Modify one of the proteins found in thale cress to glow when fentanyl binds to the receptor site.arrow_forwardPlease note whether each protein is either a Kinase (K), ATPase (A), GTPase (G), Membrane protein (M). Some proteins may need more than one letter: Dynamin [Choose ] Porin [Choose ] EGF Receptor [Choose ] CD4 [Choose ] P-glycoprotein [Choose ] Rho [Choose ] <arrow_forwardThe biomolecular interaction between protein receptors and ligands is similar to that of en- zymes and substrates, which depends in part on the shape of the protein. The shape of a protein, in turn, depends on the presence of appropriate chemical bonds in the protein. Many common medications function by altering the interactions between protein receptors and ligands, thereby interfering with the normal response of a cell to specific signals. Which of the following best describes a mechanism by which a drug might interfere with a normal cellular response? A B A medication causes the cell to become more permeable and unable to maintain the conditions that allow a normal response. с A medication interrupts the electron transport chain in a cell and makes it unable to syn- thesize sufficient ATP. D A medication enters the nucleus of a cell and alters the nucleic sequence for a specific receptor protein. A medication enters a target cell and acts as an inhibitor to an intercellular protein…arrow_forward

O ECM supports cell-to-cell communication and stem cell differentiation. O Proteoglycan complex has a unique bottle brush-like structure. It is positively (+) charged. It is composed glycosaminoglycans and carbohydrates that are attached to the proteins.
