Summary Introduction
To review :
Natural selection for resistance to rhinovirus infection in humans.
Introduction:
Rhinovirus is responsible for common cold in humans. This is the most common cause of infections in the upper respiratory tract. Its symptoms include sore throat, infection in sinuses, and ear infections. There is currently no approved antiviral agent for the treatment or prevention of the human rhinovirus infection.

Do you think a variation in the human genome that confers resistance to coronaviruses (SARS-COV-2) Will be selected for in the human population through future human generations? why or why not? Consider covid 19 morality rates, the reproductive ages of those who are most at risk, economic factors, etc. Pathogens evolve over time as well, what effect if any could this have on human evolution?

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?
Why do scientists worry more about new strains of viruses like influenza and coronviruses as potential causes of deadly human pandemics, but they never talk about the next big
Herpesvirus strain deadly pandemic? Which of the statements below helps partially answer that?
We already have effective vaccines for Herpes.
Influenza and CoV have more genes, more complex gene expression, and can undergo genetic recombination or reassortment, while Herpesviruses are more limited.
Only humans get Herpesviruses, while animals can get Influenza viruses and Coronaviruses.
dsDNA viruses aren't very transmissible and even when they are, they're not deadly.
Influenza and CoV are RNA viruses which results in having higher mutation rates -- they can more easily jump between host species. Herpesviruses are dsDNA viruses and usually
very host specific.

- What is the relationship between pandemics and evolution? Use the word: mutationarrow_forwardWhich of the following statements accurately describes what we learned about HIV evolution? a. HIV is more deadly in Northern Europe, but more transmissible in Africa. That is why there are more individuals infected with the illness in Africa. b. HIV shares a most recently common ancestor with Simian Immunodeficiency Virus (SIV) such that SIV evolved as it host-switched from chimpanzees and gorillas into humans multiple times. c. Drug development is exceedingly difficult because there are very few drug targets for HIV and AZT (a reverse transcriptase inhibitor) alone is the single most effective treatment for HIV. d. Evolution of HIV virions within a person is quite slow such that a blood draw after 1 year of infection would reveal that every single virion would have the exact same sequence.arrow_forwardEach year, hundreds of millions of people get sick from diseases like Zika, Dengue Fever, and Yellow Fever that are spread by mosquitoes. Some scientists are investigating the possibility of curbing these mosquito-borne diseases by genetically modifying the mosquitoes, such that they become less able to either reproduce or to carry the disease-causing microbes. Should genetically modified mosquitoes be released into the environment to combat these viruses?arrow_forward
- It’s late summer and a new influenza virus strain has appeared in chickens across the country.It’s an H1N1 strain of Influenza A, like the Spanish flu that caused one of the deadliest pandemics in humanhistory, back in 1918. In that case too it started as an avian flu that mutated and jumped directly from birdsto humans.You are a researcher at the NIH and the President gives you 24 hours to predict the chances that this couldturn into the next “Spanish flu”. They also ask you to present a plan for a vaccine that will specifically targetthis new strain.The full sequence of the Spanish flu virus is available and is also known which mutations where key toconfer it both high infectivity and high virulence. Also the frequency of mutations of this family of viruses isknown.Samples of the new strain currently infecting chickens are also available to you.You are at the NIH laboratories in Bethesda, MD, and you have infinite resources (equipment and staff) atyour disposal.Remember: Influenza…arrow_forwardHow do evidences happening in recent times support Evolutionary ideas?1.

Drive the mosquito population to extinction? 2. Replace the mosquito population with genetically modified mosquitoes that can not transmit malaria?arrow_forward
- You are helping a patient who you think has CJD. They want you to explain how this happened. Which explanation below is NOT correct? O spontaneous misfolding of the normal prion with age O possible transfer of abnormal prions on contaminated surgical instruments O overuse of antibiotics O possible transfer of abnormal prions from blood transfusion O possible transfer of prions through organ transplant O consumption of beef from cattle with BSE Question 65 Below are stens in the evolution/emergenco of vCDarrow_forwardSuppose that a time machine allows you to go back in time (and to travel to Australia), and you have collected rabbits and Myxoma from the years 1955 and 1980. Once you are back in the twenty-first century, you infect both sets of rabbits with both sets of Myxoma viruses. The most likely result will be (1) that the rabbits from 1955 injected with the 1955 virus will have a survival rate than those same rabbits injected with the 1980 virus; and (2) that the rabbits from 1955 injected with the 1980 virus will have a survival rate than rabbits from 1980 injected with the 1980 virus.. A. lower; lower B. lower; higher C. higher; lower O D. higher; higher E. the survival rates will be the same in experiments (1) and (2)arrow_forward"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…arrow_forward
- What cells does HIV infect? Explain how HIV enters these cells HIV is a retrovirus. What do retroviruses do once they have entered a host cell? Why is there little to no immune response following infection by HIV? Why is it difficult to diagnose? What is the difference between HIV and AIDS? How does HIV lead to AIDS? How is HIV transmitted? There isn't a drug to cure HIV although drugs are used to keep the viral load low to prevent regression into AIDS. Explain how these drugs work.arrow_forwardCan 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.arrow_forwardIf it is possible asnwer all the following questions, if not, i would like to know about question 2 and question 3. thank you. 1. Why is the statement, humans evolved from monkeys, incorrect? 2. In recent years, strains of bacteria resistant to antibiotics have created serious health care challenges for our society. Based on what you've learned about natural selection, explain how the overuse of antibiotics could influence the evolution of bacterial diseases. 3. How does the peppered moth example demonstrate that evolution is directional? 4. Is is viable to believe both in creation and evolutionarrow_forward
