- Flow cytometry analysis was performed on the blood of an individual known to have been recently exposed to both rhinovirus (RV) and Mycobacterium tuberculosis (M.tb; an intracellular bacterial pathogen). Although an effective T cell response against RV was detected, a T cell response against M.tb was absent. Subsequently, genetic testing was performed, and the individual was found to possess two mutations. Below, indicate the MOST LIKELY mutations. A. T-bet; IL-12 B. CD28: IL-2Ra C. RORyT: IL-17 D. CD3: CD4Moderna and Pfizer vaccines for COVID-19 use mRNA to the Spike protein combined with lipids. Which of the following is/are advantages of this type of vaccine compared to an inactivated virus vaccine? Select ALL correct answers. a) The vaccine is more stable for transport. b) The vaccine does not contain the virus so it cannot give you COVID-19. c) The vaccine can be rapidly produced in a slightly different form to protect from variants of SARS-CoV-2. d) The vaccine does not need a booster.Penicillin was first used in the 1940s to treat gonorrhea infections produced by the bacterium Neisseria gonorrhoeae. In 1984, according to the CDC, fewer than 1% of gonorrhea infections were caused by penicillin-resistant N. gonorrhoeae. By 1990, more than 10% of cases were penicillin resistant and a few years later the level of resistance was 95%. Explain the various ways this resistance could be spread among the cells. Could this resistance pass to other infectious bacteria from N. gonorrhoeae?
- min+ = confers resistance to minocycline cep+ = confers resistance to cephalexin van+ = confers resistance to vancomycin The following table shows the results of your experiments. Transformation of the recipient cells was conducted, using the DNA of the donor cells. You next selected for recipient cells that had undergone transformation by plating the transformed cells on media containing minocycline. This enabled you to select for min+ cells. The min+ cells were then replica plated onto media containing cephalexin or vancomycin in order to determine the antibiotic resistance phenotypes with respect to these other two antibiotics Questions a) Of the three potential orders of these genes, which orders are possible and which are impossible based on your knowledge of the relative distance? b) Finally, determine the correct order of the three genes. Please include a DIAGRAM to illustrate how you deduced the correct gene order, as well as an explanation of your reasoning.What is the role of genomics in generating anti-SEMA3A monoclonal antibodies as a potential therapeutic antibody against GBM progression? Explain in detailed manner.During the development process of a vaccine for the newly discovered Sars-COV-2 (COVID- 19) virus, pharmaceutical companies developed two potential vaccine candidates, BNT162b2 and Ad26.COV2. Some researchers postulated that BNT162b2 will be more ef- fective than Ad26.COV2 because only BNT162b2 directly targets the protein-manufactur- ing mechanisms in the cell. To test this claim, researchers proposed an experiment in which data will be collected about the efficacy of the two vaccine candidates. In the proposed study, two groups of mice will be randomly assigned one of the vaccine candidates and then infected with the virus. Data about the severity of symptoms in each group will then be collected. Which of the following describes a potential method for measuring the dependent variable in this experimental design? A B с D measure the amount of virus administered to each group measure the time between vaccine administration and virus infection in each group measure the amount of vaccine…
