all of the following that are true regarding viruses? Oncogenic viruses stimulate uncontrolled host cell divislion. Retroviruses use the enzyme reverse transcriptase to direct the production of DNA from a single stranded RNA genome. Animal viruses can be grown in tissue cultures, embryonated eggs, and live animal hosts. The shape of a virus may be determined by elther its capsid or its envelope. Like bacteriophages, when animal viruses enter host cells, only their genomes enter while their capsids remain outside of their host cells Antiviral drugs exist that target all stages of viral replication except the production of viral nucleic acids D00000

Which statement is not true of viral replication? A lysogenic cycle kills the host cell There are six basic steps in the viral replication cycle Viral replication does not affect host cell function Newly released virions can infect adjacent cells.
When a virus enters the lysogenic stage: a. the viral DNA is replicated outside the host cell. b. it enters the host cell and kills it immediately. c. it enters the host cell, picks up host DNA, and leaves the cellunharmed. d. it sits on the host cell plasma membrane with which it coversitself and then leaves the cell. e. the viral DNA integrates into the host genome.

Which statement is true of viral replication? In the process of apoptosis, the cell survives During attachment, the virus attaches at specific sites on the cell surface The viral capsid helps the host cell produce more copies of the viral genome mRNA works outside of the host cell to produce enzymes and proteins.

Although plant viruses cannot infect humans, what are some of the ways in which they affect humans?
In this section, you were introduced to different types of viruses and viral diseases. Briefly discuss the most interesting or surprising thing you learned about viruses.
The cell is the basic unit of all living things, and viruses which are generally not considered living but have the ability to infect cells. Describe how the structure of a virus compares to the structure of a cell. You should explain (not list) at least two similarities and two differences between features of cells and viruses including a brief explanation of the function of those structures. Explain why viruses need cells.
Discuss the following statement: “Viruses exist in the twilight zone of life: outside cells they are simply dead assemblies of molecules; inside cells, however, they are alive.”
viruses:1. Why must primary cell cultures be restarted every so often when preparing primary cell cultures to observe morphological changes caused by cells infected by a virus? Why are tumor cells preferred? 2. Why are non-enveloped viruses generally more resistant to disinfectants than are enveloped viruses? 3. A public health physician isolated large number of phages from rivers used as a source of drinking water in western Africa. They physician is very concerned that humans might become ill from drinking this water, although she knows that the phages specifically attack bacteria. Why is she concerned?
