Step by step
Solved in 2 steps
- The lytic cycle of a bacteriophage can be characterized by A large number of phages are released at a time. The virus-host relationship usually lasts for generations. The viral genome replicates without destroying the host. Viral DNA is incorporated into the host genome.An antimicrobial drug binds to the HIV reverse transcriptase enzyme, preventing it from working. Which of the following is true of this drug? It would inhibit early replication steps of some viruses, but not affect normal eukaryotic cell activity. It would directly interfere with translation of some viral proteins and some eukaryotic proteins. It would block assembly/maturation steps of some viruses, and interfere with translation in eukaryotic cells. It would interfere with release of newly formed viruses from a host cell, but not affect eukaryotic cells. It would interfere with protein synthesis in bacteria, but not affect eukaryotic ribosomes. It would interfere with mRNA transcription in bacteria and viruses, but not affect eukaryotic transcription.Which of the following terms is used for the stage of viral replication primarily responsible for host range specificity? Maturation Penetration Release O Adsorption Replication
- Which of the following statements describes the lysogenic cycle of lambda (A) phage? 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. The phage DNA get destructed by the host bacteria DNAThe lytic pathway of a virus is characterized by viral DNA is incorporated into the host chromosomes. extensive transcription of viral DNA destruction of the host. Both a and b. Both b and c.Some phages have a modified replication cycle in which infected host cells continue to grow and reproduce normally. In this cycle the phage DNA incorporates into the bacterial DNA. The integrated virus is called a ________________. And the cycle is known a ____________________or ________________.
- During a lytic cycle, viral DNA replication occurs without phage production or the death of the cell while during the lysogenic cycle many copies of the phage are produced within the bacterial cell, the bacterium breaks open. Select one: True FalseWhich of the following is a similarity between viruses of bacteria (bacteriophages) and viruses of algae? These viruses will enter host cells by membrane fusion. They infect host cells by injecting nucleic acid (i.e., capsid does not enter cell) After replication in a host cell, the newly-assembled viruses will exit the cell by budding. These viruses are taken into host cells by phagocytosis.You are studying your favorite (hypothetical) bacteriophage named M277. It infects E. coli and stays dormant within the bacterial cell. How does a phage become dormant within a cell? Generally, describe the steps of infection by phage in this scenario
- Describe the infective process of a bacteriophage as it attacks a cell.Which of the following statements is TRUE concerning viral envelopes? Only viruses with envelopes have their contents enclosed by a layer containing lipids Only viruses without envelopes interact with receptor proteins on the surface of the host cell. Only viruses without envelopes can release their genetic material into the cytoplasm of the host. Only viruses with envelopes package their genetic material by engulfing it.Classify each statement as true of generalized transduction or specialized transduction. Generalized transduction Specialized transduction Answer Bank Genes transfer from random sites in the bacterial chromosome. This utilizes lysogenic phages. Genes that transfer depend on the prophage insertion site. This utilizes lytic phages. Phage inserts itself at a specific site in the bacterial chromosome. This requires accidental packaging of bacterial DNA in viral capsids.
