The Baltimore classification scheme is based on the relationship between the virus' genome and its mRNA. For the following choices, indicate which viruses woul fall into each classification: 1) require reverse transcriptase to copy the information in their own genome to DNA; 2) can replicate and be transcribed in the same manner as the cell's own genetic material; and 3) a replicative form of DNA must be produced and is used for both replication and transcription. Drag and drop choices to the bins they describe. double-stranded DNA viruses Requires reverse transcriptase double-stranded RNA viruses retroviruses double-stranded DNA viruses that have an RNA intermediate Functions similarly to cell's own genetic material plus-strand RNA viruses minus-strand RNA viruses Reset plus-strand DNA viruses Uses a replicative form of DNA Help

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?
Replication of many RNA viruses depends on RNA polymerase. The antiviral drug ribavirin does not inhibit the polymerase but instead increases its error rate. Explain how this affects the virus.

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 first electron micrograph of a virus (tobacco mosaic virus) was produced in 1939. Before that time, how did scientists know that viruses existed if they could not see them? (Hint: Early scientists called viruses “filterable agents.”)
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.
Many viruses enter host cells through receptor- mediated endocytosis, What is an advantage of this entry strategy? The virus directly enters the cytoplasm of the cell The virus is protected from recognition by white blood cells The virus only enters its target host cell type The virus can directly inject its genome into the cell’s nucleus.
The observation that the bacteria genus Chlamydia contains species that can only survive as intracellular parasites supports which viral origin hypothesis? Progressive Regressive Self-replicating Virus-first
