Question
- Based on your knowledge of the COVID-19 genome (from question 6), what step(s) in the flow of biological information (DNA to RNA to Protein) are required for an infected human cell to produce a viral protein? Does the virus need access to the nucleus for this to happen?

- Human immunodeficiency virus (HIV), the causative agent of acquired immune deficiency syndrome (AIDS) infects T-helper cells that have the CD4 receptor on their surface: gp120 RNA- Core with protein coat Envelope (a) Structure of HIV Copyright © 2001 Benjamin Cummings, an imprint of Addison Wesley Longman, Inc. Edit View Insert Format Tools Table 12pt Paragraph -Reverse transcriptase enzyme B -Capsomeres of protein coat I U Αν 2 T cell A. As shown in the above diagram, HIV attaches to a susceptible cell by a binding interaction between the gp120 protein on the virus protein and the CD4 and CXCR4 receptors on the surface of the T-helper cell. What will be the next event in the virus life cycle? B. One mechanism for transmission of HIV is direct contact during sexual activity. What is the other common mechanism of transmission? over DNA (b) HIV infecting a T cell with CD4 receptors, and CXCR4 coreceptors which are distributed over the surface of the cell T² v -CD4 receptor -CXCR4…arrow_forwardPlease help me, this is from practice, double check your answers, previous tutors got it wrongarrow_forwardTrue or False: In this trial (Hershey And Chase), since labeled viral proteins were found outside the living cell, they concluded that proteins must carry at least part of the genetic information in the virus.arrow_forward
- I need help with these questions I’ve completed for biology homework. So basically it says “A company was testing a new drug it thought it would help decrease the risk of transmission of virus from mother to fetus. In an experiment to test the drug, an investigator gave 400 pregnant female rats a small dose of the experimental drug and inocululated each type of virus known to causes disease in rats. At the same time, 400 other pregnant rats were given only the virus. All rats were given the same food and kept in similar cages. Of the rat pups born to females that received both the virus and the drug. 203 showed no symptoms of the disease; 205/rat pups born to the virus-only females showed symptoms. I wrote down the hypothesis I said the drug will decrease the rate of transmission of the virus from mother to fetus Then I wrote down independent/dependent which was the drug being independent and the transmission of virus being dependent Then I wrote the controlled variables…arrow_forwardjust answer question --- dont need explanationarrow_forwardWhich of the following about the receptor-induced conformational changes in viral fusion proteins are correct? (Select all that apply): Receptor binding to the viral fusion protein is an irreversible process that leads to membrane fusion. Proteolytic cleavage may be necessary for fusion protein activation but does not always occur at the receptor binding stage. Conformational changes induced by receptor binding can activate a fusion protein. All viral fusion proteins require receptor binding for a activation (not just for binding)arrow_forward
- All HPV are non-enveloped double stranded DNA viruses. Their genomes are circular and approximately 8 kilobase pairs in size. Most encode eight major proteins, 6 located in the “early” region and 2 in the “late” region. The “early” proteins are regulatory in function.... Can you please elaborate about the HPV genome in more detail that what I posted above? Thanks.arrow_forwardYou have just isolated the covid-19 virus. Analysis of its genome reveals that it is composed of a single stranded RNA molecule containing 24% adenine. Based on this information, what would you predict the % cytosine to be? (a) 24% (b) 26% (c) 48% (d) 52% (e ) Cannot be determined from the information givenarrow_forwardHumans often use many proteins to accomplish a single function while many viruses accomplish multiple functions with a single peptide. What is an example of a virus and its single viral protein that accomplishes multiple functions? Why is it that this virus must be so efficient (doing so much with only one protein)? Why is this not the case with humans and pathogens that are relatives of humans?arrow_forward
