1. AP site is produced from the removal of abnormal bases from the affected portions by deoxyribose phosphate lyase.
2. Lengthening of the telomeres allow the survival of cancer cells due to the heightened activity of telomerases.
3. The lagging strand produces the Okazaki fragments away from the replication forks requiring multiple primers.

- What is the best way to provide strong evidence that there is a causative relationship between two variables? A. Set up a number of experiments to ensure that the explanatory variable is truly the cause of the response variable. B. Use a bar graph to compare the means of the two variables. If they are close together, then they are related. C. Graph it on a scatterplot and find the R-squared value. If the R-squared value is close to 1.0, it proves the correlation. D. Graph it on a histogram and look for the mean of the data.arrow_forwardAnalyze the validity of the given statement. Type the word true if the statement is correct.

The breakdown of ATP provides the required energy in the catalytic action of DNA ligase and DNA helicase. * 2. Telomere shortening is repaired by telomerases by using an RNA template to lengthen the three prime overhang so primase and DNA polymerase alpha can lengthen the shortened strand. * 3. Homologous recombination repair is used in double strand-breaks where a matching chromosome is used as a template. * 4. DNA polymerase I and DNA polymerase alpha could add and remove nucleotides from the newly synthesized strand.…arrow_forwardA researcher is conducting an experiment testing whether a new pharmaceutical drug is able to effectively treat heartburn and has a physician assisting with the study involving volunteers who experience chronic heartburn. Which of the following descriptions most closely describes the control used in this study? Show answer choices The researcher has organized the patients into 4 groups, where patients either take 1 dose of the drug, 2 doses of the drug, 1 dose of the placebo, or 2 doses of the placebo. The physician asks patients to rate their heartburn discomfort on a scale from 1-10 every 5 minutes up to an hour. The physician and patients both do not know if they are receiving the actual drug or a placebo. The placebo pill contains just compressed sugar and no active drug. Patients are randomly selected and placed into the four categories.arrow_forward
- The fundamental axiom of preventive medicine suggests that: Select one: a. We should screen the population to identify those with only slightly abnormal values (e.g. blood pressure) and then treat those individuals preventatively. O O b. We should screen the population to identify those with highly abnormal values (e.g. blood pressure) and then treat only those individuals. C. We should screen the population to identify those with only slightly abnormal values (e.g. blood pressure) and then only treat those individuals who show symptoms of disease. d. We should not screen the population and identify those with highly abnormal values (e.g. blood pressure) as they become sick and then treat only those individuals.arrow_forwardIn the medical field, we encounter multiple medical emergencies on a daily basis. After reading Chapter 8 you should recognize the following as some examples of common medical emergencies: shock, wounds, burns, musculoskeletal injuries, heat- and cold-related illnesses, poisoning, snake bites, sudden illness, cerebral vascular accidents, and heart attacks. Question A: List and describe the common types of shock, then explain which one you consider to be the worst type of shock and why. Typically, wounds can be classified in two different groups: open and closed. Regarding closed wounds: Question B: What does it mean to RICE or MICE it? And when can you use these? Regarding open wounds: Question C: Choose 3 different types of open wounds and describe them. Most burns are caused by either heat, chemicals, explosions, or electricity. Question D: Describe the first-, second-, and third-degree burn classifications. Question E: List and describe the different types of fractures.
