- A researcher studies a mutation that occurs in humans and writes four facts about the mutation in a chart. 1. The mutation is caused as a result of chance. 2. The mutation leads to a genetic disease. 3. The mutation occurs in sperm cells and is passed to the next generation. 4. The mutation is not discovered or fixed by the cell's enzymes. Based on the information, the researcher concludes that the mutation is harmful. Which statement best supports the researcher's conclusion? O statement 1 O statement 2 O statement 3 O statement 4 hpWhat might best explain why the incidence of cancer increases as people age? Select one: a. mutations accumulate as people age b. cell division increases as people age c. protein synthesis increases as people age d. telomerase activity increases as people age e. ATP production increases as people ageDavid worked for a decade in a nuclear power plant. After fifteen years he has developed small cell lung cancer. David is anorexic and has lost a much of his original weight. His muscles are wasting, and he is weak. He tries to move around the house throughout the day but tires easily. It has been difficult for him to access care, and he is just starting treatment for his cancer. 1. With continued exposure to the ionizing radiation, DNA damage occurred. What are the three stages of carcinogenesis that occurred after his exposure to radiation? 2. David is a healthy and active man, and his wife often remarked on how much food he used to eat for dinner after work. What would cause the muscle wasting and weight loss now? Explain your answer using what you have learned about the metabolic changes seen with cancer. 3. Muscle weakness may result from the production of onconeural antigens. A. Explain the effects of these antigens? B. In what form would this process likely take in David’s…
- How might a mutation in the DNA result in the formation of cancer ?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?What separates cancer cells from normal cells? Describe one form of mutation that can increase the risk of a normal cell being cancerous.
- Black men are more likely to get prostate cancer than other men. You are working on a prostate cancer project. You want to isolate cancer cells from a diseased prostate and culture the cells. Akilah, your lab partner uses a procedure to isolate the prostate cancer cells. You decide you want to culture the cells for various types of biological analysis. Write up the procedure used to culture the prostate cancer cells You froze some of the prostate cancer cells for future experiments. How did you freeze the cells?Now you and your team decided to analyze the genetic material. Your lab mate isolated the DNA from the prostate cancer cells. You isolated the RNA from the prostate cancer cells. Write up the procedure you used to isolate the RNA Your lab mate does Northern blotting to visualize the RNA expression. You are interested in two genes that are overexpressed in prostate cancer cells. Write up or illustrate the procedure you used to run the Northern blot in your own words.Alex,…The current way to gauge the effectiveness of chemotherapy is to track the size of the tumor. If the tumor shrinks, the chemotherapy is said to be "working." If cancer stem cells really do act the way we think they do, what will be the new way that the effectiveness of chemotherapy will be evaluated?Ultimately, cancer kills because it spreads and disturbs homeostasis. Consider, for example, a kidney cancer that metastasizes to the lungs and liver. What are some specific aspects of homeostasis that the spreading disease could affect?
- Distinguish between the effects that radiation can have on a general body cells (somatic) and cells which form the gonads/ sex organs (germline or hereditary) when exposed to a significant dose of radiation.Why are people more likely to develop cancer as they age? Why does inheriting a mutation increase cancer risk?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.
