1

2 ?Kingdom for virus? (Prokaryota & Monera) Virus Ch 18.1 Prokaryotes = no membrane bound organelles (no nucleus or mitochondria)

3 Warts are a skin virus!

4 Virus structure : Protein Coat DNA or RNA for replication Adsorb- tion site Host specific

5 Are viruses living or non-living? Nonliving Not cells Few of lifes criteria No respiration No growth No development Can be crystalline, dormant Living Replicate (with host) Contain DNA,RNA Contain protein coat

6 4..Bacteriophage Bacteria eating virus Virus uses the bacteria as a host For Viral replication

7 Plant peach virus 5.Virus can infect Plants Animals Bacteria

8 Herpes mouth virus:

9 Chicken Pox & Polio Virus

10 Rabies virus Hepatitis B (Liver)

11 Cow pox vaccination 1749 Acquired Immunization Artificial injection of a small amount of virus Bodys immune response makes antibodies

12 Lytic Cycle (Replication) of a Virus - AVIRAL 1.Adsorption of virus onto the host 2. Insertion of Virus DNA into host cell 3. Replication of Viral DNA 4. Assembly of protein coat 5.Lysis of Host cell Membrane & release Of virus

13 Viral Replication:

14 HIV virus structure:

15 HIV Virus

16 HIV virus infects T-cells HIV virus Weakens the immune system AIDS patients die of common diseases when T cell (WBC) count falls

17 AIDS = break down of the immune system & death due to common diseases versus death by AIDS virus

18 Transduction: Viral DNA becomes inserted Into the Bacteria DNA (1/100,000 )

19 Genetic Engineering of Insulin

20 Restriction Enzymes: Made by some Bacteria
