1) 286 individuals were newly diagnosed with Human Immunodeficiency Virus in 2018 in Minnesota. Of these individuals, 76% were male. HIV is an enveloped, ssRNA virus_ Baltimore classification VI. This virus targets CD4+ cells. CD4 refers to a glycoprotein which serves as a co-receptor for T-cells, located on T-helper and T-reg immune cells. a) What part of the HIV virus allows for specificity to CD4+ cells?
Indicate whether the following sentences is either True or False and CORRECT the wrong sentences ( please answer the two questions 1 and 2) : 1. Simian Virus 40 (SV40) is an example of is a circular ssDNA belong to Polyomavirus, was first isolated from primary cell cultures derived from rhesus monkey kidneys, and activates p53. 2. SARS-COV-2 is an enveloped, icosahedral virus that is surrounded by a lipid bilayer and causes COVID-19 pandemic .

Read in eTextbook - Chapter 19 page 405 - Replicative Cycles of Animal Viruses especially see Figure 19.8 The replicative cycle of an enveloped RNA virus After reading you need to do 2 things - see A and B below. A) Post an original post answering the 2 questions. using at least 6-8 sentences per answer. question 1: what are 2 good potential targets in SARS-CoV2 virus to stop it from functioning ? (HINT: Think antibodies targeting important viral proteins) question 2: what is the Pfizer Vaccine composed of? what does it target in SARS-CoV2 virus? Can you connect it to any concept from Ch 17 in your course?
Rhinovirus, the most common cause of colds, do not have a lipid envelope. Compared to enveloped viruses these and other nonenveloped viruses tend to remain infectious outside the body longer, are more likely to be spread by contact with surfaces, and are likely to be rendered harmless by exposure to hand sanitizer or hand washing. Explain how the lack of an envelope could contribute to these characteristics.
Viruses can easily mutate exchange genetic material, mechanisms referred to as antigenic drift and antigenic shift. These changes allow the virus to evade the immune system defenses. Match each term with the correct definition Antigenic drift [ Choose ] [Choose ] Different strains of a virus or strain of different viruses, combine and form a new strain that now has a mixture of the surface antigens Antigenic shift The virus changes genetically by accumulating mutations within the genes that code for antibody-binding sites

Using PEN and PAPER ONLY, illustrate a SARS-CoV-2 virion. Label the ssRNA and the 4 structuralproteins. Indicate (write) the structural protein that has significant gene mutations in the Omicronvariant and that make the virus more contagious.
What is the mode of replication of the virus? (this can be presented as a diagram with narrative description) What are its differences from HIV?
Can you please pick the right answer in each parentheses? The spike protein of SARS-CoV-2 is a carbohydrate-modified protein that ["bind the RNA genome of the virus", "", "is on the surface of the viral particle", ""] and plays a role in both ["replication of the viral genome", "recognition of host cell"] and ["packaging of viral genome for export", "fusion of viral envelope with host cell plasma membrane"] . Importantly, earlier work on spike proteins from other corona viruses showed that this molecule ["remarkable resistance to immune response", "shows remarkable conformational changes"] and only one of these served as a good antigen for vaccine development. A critical discovery in advancing the development of our current vaccines was determining what changes in the amino acid sequence would ["block degradation of the spike protein", "stabilize the conformation of the protein found on the viral particle"].
