Chapter 13 study guide Flashcards
Differentiate a virus from a bacterium
A
Describe the composition of both enveloped and a nonenveloped viruses
A
Discuss the different approaches employed to visualize viruses
A
Name and recognize different viral shapes
A
Explain how viruses can be classified either taxonomically or using the Baltimore scheme
A
Explain the 7 classes of viruses in Baltimore’s Scheme make mRNA and replicated the genome for new viral particles
A
Explain and be able to apply the rules for naming viruses
A
Define viral species
A
Name the viral families that cause disease in humans and recognize which of the seven Baltimore classes they belong, whether they are enveloped or naked, and whether the genome is segmented. For some families, name the species of an important pathogenic member
-Define virulent phage, temperate phage, prophage, lysogen, prophage induction and lysogenic conversion
A
Describe the lytic cycle of T-even bacteriophages
A
Describe the lysogneic cycle of bacteriophage lambda
A
Explain the process of bacteriophage lambda induction
A
Compare and contrast specialized and generalized transduction
A
Discuss the 7 steps of virus replication
A
Compare and contrast the multiplication cycle of DNA- and RNA-containing animal viruses
A
Explain the one-step viral growth curve and define the distinct periods
A
Discuss why it is important to know how pathogenic viruses transcribes and replicates its genome
A
Discuss the integration of animal viruses into the host genome
A
Distinguish between latent and persistent infections
A
Describe how bacteriophages are grown and quantified
A
Distinguish between primary cells and cell lines
A
Describe how animal viruses are grown and quantified
A
Discuss the use of embryonate eggs and animals as hosts for human pathogenic viruses
A
Describe the techniques used to identify viruses
A
Define cellular tropism, tissue tropism, host range and distinguish between them.
A
Discuss the relationship between viral surface proteins and tissue tropism, host range and host immune response
A
Explain why influenza virus has broad host tropism and why this is problematic for our immune system
A
Define oncogene, proto-oncogene, transformed cell, tumor-specific antigen and T-antigen
A
Discuss the relationship between DNA- and RNA-containing viruses and cancer
A
Differentiate between viruses, visions, virusoids, and prions
