    e. 1-10 μm
  2. A structural component that is found in all viruses is:
    a.The envelope
    b. DNA
    c. Capsid
    d. Tail fibers
    e. Spikes
  3. A chemical component that is found in all viruses is:
    b. Lipid
    c. DNA
    d. RNA
    e. Glycoproteins
  4. A common polyhedral capsid shape of viruses is a :
    b. Cube

    d. Pyramid
    e. Sphere
  5. Enteroviruses differ from rhinoviruses mainly in their:
    a.Type of nucleic acid
    b. Size
    c. Capsid shape
    d. Ability to survive acidic conditions

  6. Viruses that can remain latent (usually in neurons) for many years are most likely:
    b. Herpesviruses
    c. Enteroviruses
    d. Rhinoviruses

  7. What types of viruses contain the enzyme lysozyme to aid in their infection?
    b. Animal Viruses
    c. Plant Viruses
    d. Fungal Viruses
    e. Human Viruses
  8. Bacteriophages are readily counted by the process of:
    b. ELISA
    c. Plaque assays
    d. Tissue cell culture
    e. Electron Microscopy
  9. A type of cell culture that can reproduce for an extended number of generations and is used to support viral replication is a :
    a. Primary cell culture
    b. Continuous cell line
    c. Cell strain
    d. Diploid fibroblast cell
    e. Connective tissue
  10. Which of the following is not an RNA virus?

    I am not sure about all answers, but i tried to reach without any assistance (like a guess)
    1- retrovirus
    2- hepatitis A
    3- hepatitis D
    4- b
    5- d
    6- c
    7- d

  2. bidur says:

    Asma i appreciate your answers but for question no. 1, you fall prey to trap answer. The right answer is not retrovirus. for question number 2 and three you have given right answer and the rest of the answer is wrong,wish you give right answer to all the questions in next try.

  3. Asma says:

    then first i have to read about Hepatitis in detail
