QUESTION 12: In the Spring of 2009, a novel H1N1 virus emerged that had a new combination of genes from pigs, humans, and birds. As a result, the virus spread quickly, resulting in a swine flu pandemic. Which of the following concepts explains why the outbreak occurred?

A. Antigenic shift
B. Antigenic drift
C. Attenuation
D. Narrow tropism

QUESTION 1: The rabies virus primarily affects the nervous system. The specificity that the rabies virus has for neuronal host cells is primarily dictated by __________________________.

A. the helical shape of its viral capsid
B. the type of nucleic acid used for its viral genome (single-stranded, antisense RNA)
C. the spikes that protrude from its viral envelope
D. the segmented nature of its viral genome

QUESTION 2: Which of the following genome types has been observed in viruses? To be marked correct, you'll need to select all true statements, as there may be more than one correct answer.

A. Single-stranded RNA
B. Single-stranded DNA
C. Double-stranded RNA
D. Protein-based

QUESTION 3: Choose the correct statement about viral evolution.

A. RNA and DNA viral genomes evolve at equal rates.
B. Cellular genomes mutate at a faster rate than viral genomes due to their large size and increased chance of replicative mistakes.
C. DNA viruses mutate faster than RNA viruses because thymine is more susceptible to mutation than uracil.

D. RNA viruses mutate faster than DNA viruses due to a lack of proofreading replicative enzymes.

QUESTION 4: Your elderly patient is affected by shingles. After careful observation, you note that the virus responsible for the infection has an icosahedral capsid, is enveloped, and has double-stranded linear DNA as its genetic material. Based on this information, in which of the following viral families would you group this viral pathogen?

A. Hepadnaviridae
B. Parvoviridae
C. Coronaviridae
D. Herpesviridae

QUESTION 5: Which of the following is a key difference between lytic and lysogenic bacteriophage replication cycles?

A. Lysogenic bacteriophages release via host cell lysis, whereas lytic bacteriophages bud off from the host cell membrane.
B. The lytic replication cycle ends with host cell lysis and release of newly formed bacteriophage particles, whereas lysogenic replication leads to prophage formation.
C. Lytic replication requires an uncoating step, whereas in lysogenic replication, the bacteriophage's nucleic acid is directly injected into the host cell.

D. Whereas lytic replication enables the infection of several hosts, lysogenic replication only allows for infection of a single host cell.

QUESTION 6: Which of the following is an unsuitable culture method for an animal virus?

A. Direct inoculation of virus onto blood agar
B. Live animal inoculation
C. Tissue culture method
D. Injection of virus into embryonated eggs

So, I am in need of some basic points for writing this essay, withscientific sources/websites referenced/given to me so that I canlook them over. Write me the whole paper, and you'll get all thepoints...write some main points/give me websites to refer to andget partial points. I don't care which position you take, as longas it is backed up with some sources.

______________________________________________


After reading the scenario described below, imagine that you are anexpert in viruses, the immune system, and epidemics. As an expertyou are asked to explain in language everyone can understand thescientific basis supporting one of the two positions below. Youressay should be a minimum of two pages, double-spaced.

A new strain of avian (bird) virus has popped up in China and hashealth officials at the World Health Organization are worried. Theyfear it may jump across species and infect humans, causing apandemic. The virus is 100% lethal in birds, killing them within 24to 48 hours. A human vaccine against the avian virus has beensuccessfully manufactured in the U.S. and there is enough toinoculate the entire U.S. population. You are a scientist at theCenter for Disease Control and have been called before Congresswhere they are debating whether to make immunizations against thisavian flu legally mandatory for all US citizens.

Ignoring the constitutionality of such a law, choose one of thefollowing positions and, in writing, present a scientificallypersuasive case for why Congress should adopt your position. If youchoose position 2, then, in addition to making a persuasiveargument for why this is the case, please state what thealternative strategy should be.

Position 1: To prevent a lethal epidemic in the United states allthose living in the U.S. must receive the vaccine.

Position 2: One can protect the entire U.S. population against anepidemic without having to vaccinate everyone.
