Chapter 13, Problem 4SA
Summary Introduction
To answer:
The four different ways viral
Introduction:
The viruses are obligate organisms that show signs of life only inside a host. Outside the host, they either die or do not show any sign of life. They invade the host cell to carry out their function like replication. A particular virus infects a particular host cell. The invaded host cell acts as machinery for the viruses.

- Host specificity of a virus is due to O 1) similarities in size between the virus and the host cell. O 2) the presence or absence of a cell wall on the host cell. O 3) particular genes that it shares with the infected cell. 4) compatibility between viral and cellular surface molecules. 5) the presence of an envelope.arrow_forwardClassification of viruses is based on all of the following excepta) type of nucleic acid. b) shape of virus.c) size of virus. d) host infected.e) strandedness of nucleic acid.arrow_forwardList three differences between the structure of HIV and the virus that causes influenza. For one of these differences, explain how the STRUCTURE is key to the FUNCTION of the virus.arrow_forward
- A viral particle adsorbs onto a host cell membrane. It uncoats and releases its single-stranded nonsegmented nucleic acid into the cytoplasm where it is immed dependent RNA polymerase, into mRNA. It is then translated into viral structural proteins and enzymes.

- What probably plays the most important role in determining the tissue and host specificity of viruses? Give some specific examples.arrow_forwardDefine the terms "latency" and "lysogeny" as they refer to viruses. Describe at least TWO ways these two processes are similar. Describe at least TWO ways these two processes are different.arrow_forwardIn electron micrographs of HSV infection, it can be seen that the intact virus initially reacts with cell-surface proteoglycans, then with specific receptors. This is later followed by viral capsids docking with nuclear pores. Afterward, the capsids go from being full to being "empty." Which of the following statements best fits these observations? The viral envelope is not required for infectivity, since the envelope does not enter the nucleus. The viral envelope mediates entry into the cell, the capsid mediates entry into the nuclear membrane, and the genome is all that enters the nucleus. Only the genetic material of the virus is involved in the cell's infectivity, and is injected into the host cell like the genome of a phage. Viral capsids are needed for the cell to become infected; since the full capsids enter the nucleus.arrow_forward
