Across
- 2. evolution occurs at this level which only includes one species
- 3. the type of selection in which both extremes are favored
- 4. the name for the protein coat covering the genetic material
- 7. produces a protein using RNA nucleotides
- 8. an abrupt, major change that has the potential to cause pandemics
- 10. some viruses have this covering the protein coat
- 12. produces a copy of DNA using RNA nucleotides
- 13. a recipe for a protein
Down
- 1. the type of selection in which one extreme of the phenotype is favored
- 3. small changes in virus genes that produces viruses that are closely related
- 5. step in the replication cycle is when the virus recognizes and binds to its host cell
- 6. a protein that binds to a pathogen to trigger an immune response
- 9. a part of a foreign object that an antibody recognizes
- 11. a variation of the lytic cycle; the virus integrates into the DNA of the host cell
