Do not just copy it from somwhere.
Step by step
Solved in 2 steps
- In the extraordinary times in which we live, biotechnology is playing a vital role in helping to identify and contain coronavirus, SARS-CoV-2, outbreaks around the world. There are three tools that are fundamental to many areas of biological research: DNA isolation, polymerase chain reaction (PCR) and gel electrophoresis. Write an essay that outlines the key steps in testing for active SARS-CoV-2 (the coronavirus responsible for causing Covid-19) in a patient. Begin with a brief description of how the sample is collected and follow with a description of each of the biotechnology procedures that are used to determine if the patient’s sample contains SARS-CoV-2.Which of the following methods is involved in determining the linkage group or genetic map in humans? 1)synteny testing 2) tetrad analysis 3) chiasmata analyses 4) bromodeoxyuridine 5)zygotene and pachytene DNA synthesisThe complete coronavirus genome sequence from the first known patient infected with SARS-CoV-2 was published on January 10th 2020, just a short time after the patient had been hospitalized in China with respiratory symptoms. They did this so quickly using nanopore sequencing. Scientists compared the genome sequence from the new coronavirus (SARS-CoV-2) with the genome sequences from several other coronaviruses and they did identify a sequence unique to the SARS-CoV-2 strain. This unique sequence was in the N gene of the viral genome. What protein is made from the N gene of the virus?
- Answer the following questions: 1. Null vs Alternative Hypothesis • Definition & connotations • How do they differ? • How do you state them? 2. Types of Error • Define Types I and II Errors • How do they differ from one another? • What are the implications of each error? • What are the synonyms and connotations associated with them? • If the hypothesis is about a pernicious bacterium. which is the safer error to make?Topic is SARS-CoV-2 Describe how mutations or genetic variation contributed to either: the evolution of your pathogen (or) the host’s chance of resisting the pathogen or surviving the infection If applicable, you can also discuss how genetic variation or mutation have made it difficult (or easy) to treat infection caused by your pathogen.3.) A number of publications explain an expanding knowledge on the genetics and genomics of SARS-CoV-2 and its implications for understanding COVID-19. Why should a healthcare professional need to have a solid understanding of these basic genetics and genetic engineering terms? How would this knowledge help you in your nursing practice? 4.) Scientists and researchers are using genetic engineering rather than traditional methods in developing COVID-19 vaccines. In a tabular format give at least 2 examples of vaccines that uses genetic technology and describe each in terms of: a. Target Population b. Vaccine Efficacy C. Vaccine administration d. Possible side effects Storage requirements e.
- 1. How does evolution helps in understanding the probable origin of SARS-CoV-2? Discuss and explain it thoroughly. Do no just copy it from somewhere, I need a comprehensive explanation for this.1) Explain 2 contributions of G. Borelli and Y. C. Fung to Biomechanics.2) How do you think that elements of Biomechanics can be used in studiesenvironmental? Explain with 3 examples.3) Name 5 research areas where Biomechanics is involved. In one of them explain the relevance from the biological point of view of determining forces and deformations.4) What are the different scales where biomechanics concepts are applied? Give an example for each of them.5) Briefly explain three general functions of the muscles and bones of the musculoskeletal system.6) Most of the muscles of the skeleton are attached to areas very close to the joints, so that their arms, although they are very small, their mechanisms allow the movement of the human body. (a) How are they considered from the point of view of force efficiency? (b) What are the biomechanical benefits?7) Why are bones considered efficient structures from a biomechanical point of view?This article highlights a young doctor at Elmhurst Hospital during the beginning of Covid-19 pandemic. Dr. Zikry is quoted as saying: “It’s become very clear to me what a socioeconomic disease this is...”. In addition, the textbook discusses the personal variables and socioeconomic status (SES) that are used to find patterns in disease (pp.112-118). What do you think Dr. Zikry meant by referring to the SES of his patients? Why was it important to find a pattern of personal variables and SES among the of victims of Covid-19 at the beginning of the pandemic?
- Discuss how the SARS-CoV-2 virus causes Covid-19 disease became a "new" zoonotic disease and has resulted in a "fast" spreading World-Wide Pandemic. how has it evolute as a zoonotic disease, the mechanism of infection in humans, symptoms of disease, treatment and prevention. Describe how to "flatten" the curve and make the epidemic a "slow" epidemic by acting as a "social" vaccine.Describe the natural history of the Rabies (taxon:11292) : host infectivity, transmission, symptomology Describe the genomic structure of the Rabies (taxon:11292)virus Baltimore Classification of Viruses What is the genome made of? What are the genes? How are they organized? Is the genome single stranded, double stranded, RNA, DNA and what does it mean to be + or - strand? Is it segmented and what does that mean?Due to the lack of any antiviral for a newly emergent virus, blood harvested from individuals who were infected by the virus and subsequently fully recovered without hospitalization is in a clinical trial to treat individuals who are very sick by the virus. The donors have been carefully screened to eliminate their possibility as carriers (in their blood) of any virus. Which of the followings is the best strategy for this clinical trial: generating sera from the donors' blood and injected them i.v. to the recipients whose blood types are matched to those of the donors matching blood type of the donors and recipients before blood transfusion generating sera from the donors' blood and injected them intravenously (i.v.) to the recipients without worrying about the matching of their blood types there are more than 1 correct answers in the other choices
