  1. 2. Some ____ viruses do not become incorporated into host chromosome hang out in the cell
  2. 4. Each strand of DNA serves as template for its complement(except for certain viruses such as Hep B virus, which synthesizes RNA to act as the template for new DNA)
  3. 5. division Genes for _________ ________ "turned off" or genes inhibiting division "turned on"
  4. 6. Removal of capsid by cell enzymes
  5. 7. encephalopathies. Large vacuoles form in brain. Characteristics spongy appearence. BSE,vCJD, and kuru.
  6. 9. -ssRNA complementary to the genome is synthesized by viral RNA polymerase in the cytoplasm to act as template
  7. 10. Capsid enters cell by direct penetration, fusion, or endocytosis
  8. 11. +RNA(mRNA)complementary to the genome

  1. 1. Chemical attraction between viral protein and host cell receptor
  2. 3. Each type of animal virus requires different strategy depending on its nucleic acid
  3. 4. Each strand of genome acts as template for synthesis of its complement by viral RNA polymerase
  4. 7. Complementary strand of DNA is synthesized to act as a template for synthesis in the nucleus
  5. 8. Enveloped viruses cause persistent infections. Naked viruses are _____ by exocytosis or lysis.
  6. 12. DNA viruses in nucleus and in RNA viruses develop solely in cytoplasm. Number of viruses produced depends on type of virus and size and initial health of host cell.
