Across
  1. 2. Nucleic acid surrounded by protein coat
  2. 6. created concept of a virus
  3. 9. phage reproductive cycle that culminates in death of the host cell
  4. 11. allows replication of the phage genome without destroying the host
  5. 12. membranous envelope that surrounds the capsid
  6. 14. protein shell enclosing viral genome
Down
  1. 1. viral DNA integrated into the bacterial chromosome by viral proteins that break both circular DNA molecules and join them together
  2. 3. protein subunits that make the protein shell enclosing the viral genome
  3. 4. infectious agent that is a misfolded version of a normal cellular protein, and appear to increase in number by converting correctly folded versions of the protein to more prions
  4. 5. phage that reproduces only by a lytic cycle
  5. 7. phages that can use both the lytic cycle and the lysogenic cycle
  6. 8. limited variety of hosts that a virus can infect
  7. 10. viruses that infect bacteria
  8. 12. circular RNA molecules that infect plants
  9. 13. RNA virus that reproduce by transcribing its RNA into DNA and then inserting the DNA into a cellular chromosome
