Cell Biology 2 - Medically Relevant Viruses

  1. What is the structure of the Virion?
    Naked and Enveloped?
    Image Upload 2
  2. What is the replication cycle of a bacteriophage?
    Image Upload 4
  3. How does adsorption and penetration by a bacteriophage work?
    Image Upload 6
  4. How can a virus infect a cell?
    A virus can only infect a cell if it can interact with a specific receptor on its plasma membrane.

    The presence of receptors delimits the virus host range

    The receptor is a normal surface protein or lipid component of the host cell, often involved in cell-cell recognition and the immune system.

    Animal viruses enter by receptor-mediated endocytosis or by membrane fusion.
  5. How do viruses enter cells by receptor-meditated endocytosis?

  6. How do viruses enter by membrane fusion?
    Image Upload 10
  7. What is the time course of events in T4 phage infection?
    What are early viral proteins and what are late viral proteins?
    Image Upload 12
  8. How are viruses categorised?
    Image Upload 14
  9. How do class 1 viruses replicate: ds DNA Genome?
    The host cell enzymes transcribe the viral DNA into mRNA and translate viral proteins.

    Virally-encoded DNA polymerase then replicates the viral genome

    Animal Viruses: Adenovirus Papillomavirus, Herpes Virus
