Question 1-What SARS viral proteins are made using the frameshifting? Is there only one SARS viral protein made using frameshifting or are there many proteins made using frameshifting?
Question 2-The VVOW the week demonstrates the mechanism by which a simple virus can randomly self-assemble. The assembly of more complex viruses is driven by binding of viral subunits to the genome or cellular membranes. How does this facilitate assembly compared to the video? Explain using a specific virus as an example (with pictures if possible).
Question 3-Read the review article by DeSouza and Summers about how retroviruses select their genome. What did you learn from this paper? Describe how retroviruses selectively package their genome and specifically assemble viral proteins within their capsids that are critical for viral infectivity.
Question 4-Compare and contrast the requirements and steps involved in the assembly, exit and maturation of enveloped vs non-enveloped viruses. What are the consequences to the host cell of each mechanism?
Question 5-Viral proteases and glycosidases are excellent targets for therapeutic intervention of viral infections. Describe steps in the lifecycle of a specific virus that requires viral proteases/glycosidase for formation of infectious virions.
Lymphosum values are usually above 92%. What if the lymphosum value was low? What conclusion can you come up with? Why is it low?
Horace Jones had a colonoscopy shortly after his 50th birthday, and the gastroenterologist noticed an unusual mass of tissue in the region of the sigmoid colon.
You trap and mark 400 field mice in one week. Later you come back and capture 200 field mice. Of the 200 captured in the second effort, 150 are recaptures.
What is the difference between an intermediate host and a definitive host? Identify each host in the life cycle of the causative agent of malaria?
What information does it not provide that may be useful for deciding on conservation efforts. What are the genotypes of the parents.
A scientist was working on "specific toxic material" and he had identified that because of this toxin, cytoplasmic levels of cAMP was increased and this elevated levels disturbed overall homeostasis of living system
Identify two differences between the bacteria and protist kingdom. If you were testing the effects of different brands of fertilizer to detemine which one promoted best growth over six weeks.
A very heavy rainstorm floods a mountain river, changing its course and digging a deep canyon through the soft soils of the meadow in the valley below. What happens to the mice on either side of the valley?
Lipid metabolites are often seen as key elements in cellular signaling. Is this unique? Please provide several examples of the function of lipids as key elements in signal arrays and list the biologic functions these signals affect?
q1. volcanoes are usually not preserved in the geologic rock record as they are generally eroded away. though the
Explain the difference between allopatricand sympatric speciation gene flow, reproductive isolation, genetic mutation, allele frequencies, and subpopulation. Finally, give a detailed example of how each type of speciation might occur.
You receive a set of pregnant brown mice. You know that the mothers are doubly heterozygous (heterozygous at both the coat color and albinism loci) and that the fathers were albino.
