  2. Virus • The nonliving Undead

  3. Virus Characteristics • About as big as a protein • Basic Virus Anatomy • outer protein coat • Inner core of nucleic acid

  4. Viruses cannot reproduce on their own

  5. Kinds of Viruses: • -Viruses cannot be stopped using antibiotics because they are non-living particles!

  6. Virus reproduction • They cannot reproduce outside of a living cell! • Host specific • Rabbit viruses only infect specific rabbit spp • HIV only infects certain white blood cells • They cannot reproduce outside of a living cell!

  7. Virus Reproduction • 1.) attach to host cell • 2.) viral DNA or RNA enters cell • 3.) viral DNA or RNA codes for proteins and enzymes of the virus

  8. LyticvsLysogenic • Lysogenic – latent period – not actively producing viruses • Lytic – producing more viruses… like crazy!

  9. Retrovirus • Viruses that carry RNA • Also have enzyme called reverse transcriptase • RNA  DNA, • Than DNA is incorporated into host’s DNA,

  10. Prions… yikes! • Verdi Is our favorite! • -Jon
