Viral genomes vary greatly in size and may include from four genes to several hundred genes. Which of the following
viral features is most apt to correlate with the size of the genome?

B) RNA versus DNA genome
C) double- versus single-strand genomes
D) size and shape of the capsid
E) glycoproteins of the envelope
D) size and shape of the capsid
Viral envelopes can best be analyzed with which of the following techniques?

B) antibodies against specific proteins not found in the host membranes
C) staining and visualization with the light microscope
D) use of plaque assays for quantitative measurement of viral titer
E) immunofluorescent tagging of capsid proteins

D) the enzymes produced by the virus before it infects the cell.
E) the proteins on its surface and that of the host.
E) the proteins on its surface and that of the host.
4) Most human-infecting viruses are maintained in the human population only. However, a zoonosis is a disease that is
transmitted from other vertebrates to humans, at least sporadically, without requiring viral mutation. Which of the
following is the best example of a zoonosis?

E) copies of the herpesvirus genome permanently maintained in host cell cytoplasm
D) copies of the herpesvirus genome permanently maintained in host nuclei
In many ways, the regulation of the genes of a particular group of viruses will be similar to the regulation of the host
genes. Therefore, which of the following would you expect of the genes of the bacteriophage?
A) regulation via acetylation of histones
