  1. BACTERIAThe Good, The Bad, The Ugly

  2. Eubacteria • Domain- Bacteria • Kingdom- Eubacteria

  3. Common Characteristics • Prokaryotic cells • Unicellular • Autotroph or heterotroph • Replicate Asexually • Cell is a complex structure

  4. Key Characteristics • Found more in people and foods than in nature • Cell wall made of peptidogylcan • Treated by antibiotics -ex. Strep Throat

  5. Archaebacteria • Domain- Archaea • Kingdom- Archaebacteria

  6. Common Characteristics • -Prokaryotic cells • -Unicellular • -Autotroph or heterotroph • -Replicate Asexually • -Cell is a simple structure

  7. More ancient than eubacteria • No peptidogylcan in cell walls • Known as Extremophiles because they are mostly found in extreme environments • Ex. Boiling hot springs, salty lakes, thermal vents, mud of marshes where there is no oxygen

  8. Is it alive or is it dead……. http://player.discoveryeducation.com/index.cfm?guidAssetId=74661262-5142-4962-B4D7-C16E7136D01D&blnFromSearch=1&productcode=US

  10. Characteristics of Viruses • Nonliving strand of genetic material within a protein coat • NO organelles • Can NOT move, make proteins, or replicate on its own - MUST rely on a host cell • Virus are so small, scientist must use electron microscopes to study them

  11. Virus Structure • All viruses are made up of: - Nucleic Acid: either RNA or DNA, NEVER both. -Capsid: outer layer made of proteins which contain and protect the genetic material • May have tail fibers and projections to aid in attachment.

  12. Replication • Replication can occur through either two cycles: - Lytic Cycle - Lysogenic Cycle • Viruses DO NOT kill cell immediately but uses the cell. • http://glencoe.mcgraw-hill.com/sites/0078802849/student_view0/unit5/chapter18/concepts_in_motion.html#

  13. Prevention • Vaccines are used to help PREVENT the replication, entry, release, etc. of viruses. • Viruses can NOT be treated, ONLY prevented. • Why are vaccines hard to make?

  14. What is a virus? • What two macromolecules make up the capsid of a virus? • Why are viruses non-living? • What do viruses inject into the host cell to get replicated? • What is a bacteriophage? • What are vaccinations made of? • Why is there no good vaccine against HIV or the common cold?
