2. Suppose that you isolated an enveloped helical RNA virus. Purified RNA from this virus is capable of supporting translation in a rabbit reticulocyte cell‑free translation system or in any other such system Further analysis indicates that this virus replication is inhibited if infected cells are incubated with protease inhibitor such as trypsin inhibitor. Based on this information, discuss the mechanism by which this virus replicates its genome in infected susceptible, permissive cells.

Suppose that you isolated an enveloped helical RNA virus.
Purified RNA from this virus is capable of supporting translation
in a rabbit reticulocyte cellfree translation system or in any
other such system Further analysis indicates that this virus
replication is inhibited if infected cells are incubated with
protease inhibitor such as trypsin inhibitor.
Based on this information, discuss the mechanism by which this
virus replicates its genome in infected susceptible, permissive
cells.

1. Suppose that you isolated an
enveloped icosahedral RNA virus. Purified RNA from this virus is
capable of supporting translation in a rabbit reticulocyte
cell‑free translation system or in any other such system. Further
analysis indicates that this virus replication is not
inhibited by actinomycin D, a strong inhibitor of
DNA-dependent RNA polymerase.
Based on this information, discuss the
mechanism by which this virus replicates its genome in infected
susceptible, permissive cells.

Why do you suppose an animal virus grown in (and then
isolated from) tissue culture might be more susceptible to
inactivation by antibody than a similar virus propagated (and then
isolated from) in an animal?
Assume you do the assay by isolating the viruses grown
in these two different environments from antibody and then seek to
compare in a controlled environment, which virus particle is
inactivated more readily by the presence of appropriate
antibody.

You have purified genomic RNA from the following viruses: Zika,
and murine leukemia viruses. You performed an experiment where
susceptible, permissive cells were separately transfected with one
pure molecule of viral RNA. Which RNA will lead to a productive
viral infection? Discuss the reasons why one RNA succeeds and the
other fails. Be clear and convincing
Suppose a student carrying a flu virus returns to an isolated college campus of 1000 students.
Suppose a student carrying a flu virus returns to an isolated college campus of 1000 students. Determine a differential equation governing the number of students x(t) who have contracted the flu if the rate at which the disease spreads is proportional to the number of interactions between the number of students with the flu and the number of students who have not yet been exposed to it

BACKGROUND:Severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2)is an enveloped, (+)-sense, single-strandRNA virus that
causes coronavirus disease 2019(COVID-19). The coronavirus family
is named for the crown-like spikes on the outer surface of the
virus and includes viruses that infect many species of animals,
including camels, cattle, bats, and cats. The SARS-CoV-2 virus
appears to have “spilled”out ofbats,its primaryanimal host,and into
humansin December of 2019 in Wuhan, China. COVID-19 symptoms appear
2-14 days after exposure and include fever, dry cough, shortness of...

Various experiments have shown that the SARS CoV-2 is
an RNA virus that enter the human cells through a transmembrane
receptor called angiotensin converting enzyme 2 (ACE2). Polymerase
chain reaction (PCR) and genome sequencing have been cardinal in
both diagnosis and research into the COVID-19 pandemic. Currently,
DNA sequences of both SARS CoV-2 virus and susceptible human hosts
are available. As a student of molecular biology and biotechnology,
use the above information to answer the following
questions.
