Chapter 6.4, Problem 1TQ
Summary Introduction
To review :
Relative advantages and disadvantages of the slow release strategy for a virus as compared to the strategy of a temperate phage.
Introduction:
A temperate phage infects and lyses the host cell similar to the virulent phage. Additionally, the temperate phage has an alternative pathway in which the phage integrates its genome as a prophage. Lysogeny is the state in which the phage lysogenizes the host cell. An example of a temperate phage is phage lambda.

a)
dsRNA
b)
Positive ssRNA
c)
Retroviruses
d)
Negative ssRNA
b.
An antiviral drug specifically modifies viral receptors on a eukaryotic host cell. How might this affect the viral reproductive cycle?
It would enhance the process of viral apoptosis
It would result in the degeneration of the viral capsid
It would facilitate the process of viral endocytosis
It would prevent the virus from attaching to the host cell

Consider the phase variation of flagella in Salmonella. Describe the phenotype of a cell in which hin is deleted. Will it be motile? Will it undergo phase variation? Which flagellin(s) will be used, if any? Name two bacterial defenses against bacteriophages and explain how they work How might a phage evolve resistance to the CRISPR host defense?

After infection, the viral genes immediately turn the host cell into a lambda-producing factory, and the host cell then lyses. Most of the prophage genes are activated by the product of a particular prophage gene. The phage DNA is incorporated into the bacteria DNA The phage DNA is copied and exits the cell as a phage.
