distinguish between the lytic, lysogenic and slow-release viral cycles. What are the relative advantages and disadvantages of the slow-release strategy, comparee with the strategy of a temperate phage, which alternates between lysis and lysogeny?

List 3 viral classes based on their morphology. What is the difference between lytic and lysogenic cycles? How can you grow viruses in the laboratory? _________________________ viruses become integrated in to the host cell’s DNA and induce tumors.
Viruses- Bacteriology -Describe the characteristics of viruses. -Explain receptors for bacterial viruses (bacteriophage). -How do bacteria prevent the invasion of foreign nucleic acids? -What is reverse transcriptase and which viruses use it? -What type of nucleic acids is in many important human disease-causing viruses? -List the possible consequences of viral infection of an animal cell? -Differentiate between animal and bacterial viruses. -Describe both lytic and lysogenic cycles. -Explain the potential advantages of lysogeny versus lysis for a temperate virus
Review Each temperate (or lysogenic) bacteriophage (e.g., lambda, 434, P22) encodes its own repressor protein. The repressor binds to six binding sites within the phage genome. These sites can also be bound by a second transcriptional repressor encoded by the phage, called Cro. The pattern of binding of repressor and Cro to these sites determines whether the phage grows lytically or lysogenicaly. Launch the molecular model of the temperate bacteriophage repressor to explore its structure. Then, answer the questions. Launch...
What is the difference between an absolute and a relative link? What are the advantages and disadvantages of using each type? Can you give an example of how you would use an absolute link and a relative link on a website? I look forward to your reply.
