Title: ?Kingdom for virus? (Prokaryota
1?Kingdom for virus? (Prokaryota Monera)
- Virus Ch 18.1
- Prokaryotes no membrane bound organelles (no
nucleus or mitochondria)
2Warts are a skin virus!
3Virus structure
- Protein Coat
- DNA or RNA for replication
- Adsorb-tion site
- Host specific
4Are 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
54..Bacteriophage
- Bacteria eating virus
- Virus uses the bacteria as a host
- For Viral replication
6Plant peach virus
- 5.Virus can infect
- Plants
- Animals
- Bacteria
7Herpes mouth virus
8Chicken Pox Polio Virus
9Rabies virus Hepatitis B (Liver)
10Cow pox vaccination 1749
- Acquired Immunization
- Artificial injection of a small amount of virus
- Bodys immune response makes antibodies
11Lytic Cycle (Replication) of a Virus - AVIRAL
3. Replication of Viral DNA
- Adsorption of virus onto the host
5.Lysis of Host cell Membrane release Of
virus
4. Assembly of protein coat
2. Insertion of Virus DNA into host cell
12Viral Replication
13HIV virus structure
14HIV Virus
15HIV virus infects T-cells
- HIV virus Weakens the immune system
- AIDS patients die of common diseases when T
cell (WBC) count falls
16AIDS break down of the immune system death
due to common diseases versus death by AIDS virus
17Transduction
Viral DNA becomes inserted Into the Bacteria DNA
(1/100,000)
18Genetic Engineering of Insulin
19Restriction EnzymesMade by some Bacteria
