Not all Americans are willing to get the covid-19 vaccine, and not all countries have enough vaccines for all their citizens, or the capacity to distribute them. Explain how this may provide opportunities for viral evolution to occur and the potential consequences.
What are the similarities and differences between retroviruses and retrotransposons? It has been hypothesizedthat retroviruses evolved from retrotransposons. Do youagree with this model? Justify your answer
The major difference between retrotransposons and retroviruses isa. retrotransposons encode reverse transcriptase.b. retroviruses move from one site in the genome toanother.c. retroviruses encode the env gene, which allows themto move from one cell to another.d. None of the above are correct.
The evolutionary tree of HIV-1 revels that a.) The SIV strain that infects gorillas is the same strain that infects chimpanzees. b.) HIV is a monophyletic clade that originated from the same strain of SIV. c.) All of the answers are correct d.) The virus jumped from chimpanzees to humans four times. E.) western chimpanzees are more closely related to gorillas than eastern chimpanzees.
Can viruses adapt by natural selection? A. No, because there isn't a genetic basis for inheritance between parent and offspring virus particles. B. No, because there isn't a way to distinguish more fit from less fit virus particles C. Yes but only via human (domestic/artificial) selection D. No they evolve by mutations. E. Yes, virus particles that are most successful successful in reproducing quickly and infecting other host cells are the best adapted.
Give reasons why you do not need to worry about the COVID vaccines alteringyour DNA. Explain
"As the coronavirus spread globally, its genome changed — mutated — as expected for any virus. These mutations may affect the virus’s “fitness,” its ability to reproduce and spread. Some mutations weaken a virus, some have no measurable effect, and some make it stronger. There are many ways that a virus can mutate to increase its fitness. While there’s been much focus on changes in the virus’s spike proteins, which allow the coronavirus to invade cells, a virus can also sustain changes in other proteins. Such changes can allow the virus to replicate more easily or evade the immune system, for example. They may even allow the virus to persist longer in nasal passages. As a virus becomes more fit, it will outcompete less fit viruses — and Delta is not the first variant that has beat its predecessors and competitors in certain areas. There’s the Alpha variant that first became dominant in Britain, and the Gamma variant that first became dominant in Brazil. Such changes are not unique to…
In 1918, an influenza pandemic that originated with avian flu killed 50 million people. Researchers isolated samples of that virus from bodies of infected people preserved in Alaskan permafrost since 1918. From the samples, they sequenced the viral genome, then reconstructed the virus. The reconstructed virus is 39,000 times more infectious than modern influenza strains, and 100 percent lethal in mice. Understanding how this virus works can help us defend ourselves against other deadly influenza strains that arise. For example, discovering what makes it so infectious would help researchers design more effective vaccines. Critics of the research are concerned: If the virus escapes the containment facilities (even though it has not done so yet), it might cause another pandemic. Worse, terrorists could use the published DNA sequence and methods to make the virus for horrific purposes. Do you think this research makes us more or less safe?
Using retroviral vectors for gene therapy might increase the patient's risk of developing cancer because they might: a. introduce proteins from the virusb. integrate recombinant DNA into the genome in ways that misregulate the expression of genes at or near the site of integrationc. not express the genes that were introduced into a patient's cellsd. not integrate their recombinant DNA into the patient's genome
A" is a retrovirus. It can integrate DNA into random sites of human genome. Another virus "B" can integrate DNA at a specific site of human genome. Which one of these viruses would make a better vector for gene therapy? Briefly explain.
Please consider the figure attached i. The ordinate (i.e., 'y-axis') represents values for the C or G nucleotide base proportion in sequences (or, in this case, genomes).ii. Influenza viruses that infected birds or moved from birds to humans without spreading are characterised by higher A + U content relative to influenza viruses that infected humans for long time periods.iii. Influenza viruses adapted to human hosts are characterised by lower G + C content relative to influenza viruses that infected birds or moved from birds to humans without spreading. iv. Human and swine influenza A H1N1 strains evolved from a birdlike G + C state to a humanlike G + C state since 1918. v. Data such as those depicted in the figure have been interpreted as evidence that the 1918 influenza virus strain originated from a bird influenza virus population. Question 1 options: A) Statement ii conveys accurate information. B) Statements ii,…
