You have recently isolated a virus associated with a human disease. The virus particles are spherical, ~100 nm in diameter, and possess an envelope. Would you expect to find glycoproteins in the viral envelope? yes Would knowing that the particles are spherical mean that they are built with icosahedral symmetry? [Select]

A DNA sequence consists of a string of elements called nucleotides, in a defined order. Suppose the DNA sequence of a virus is 20 nucleotides long. If each nucleotide can be either a G, T, C, or A, how many different sequences are possible?
DNA from a newly discovered virus was purified, and UV light absorption was followed as the molecule was slowly heated. The absorbance increase at the melting temperature was only 10%. What does this result tell you about the structure of the viral DNA?
A cell is infected with an HIV mutant that results in very little virus being released into the medium that is used to grow the cultured cells. Upon electron microscopy it is noted that the membrane of the infected cell is idenitcal in appearance to a cell that has not been infected. In addition there is relatively little viral RNA in the cells and relatively few proviruses in the cellular genome when compared to a non-mutant HIV infection. Which of the following proteins is most likely mutated? Multiple Choice gag reverse transcriptase vif vpu
