?Kingdom for virus?
(Prokaryota & Monera)
Virus Ch 18.1
Prokaryotes = no membrane
bound organelles (no nucleus
or mitochondria)
Warts are a skin virus!
Virus structure:




Protein
Coat
DNA or
RNA for
replication
Adsorbtion site
Host
specific
Are viruses living or non-living?
Nonliving
 Not cells
 Few of life’s
criteria
 No respiration
 No growth
 No development
 Can be
crystalline,
dormant
Living
 Replicate (with
host)
 Contain DNA,RNA
 Contain protein
coat
4..Bacteriophage
 Bacteria
“eating” virus
 Virus uses the
bacteria as a
host
 For Viral
replication
Plant peach virus
5.Virus can
infect
 Plants
 Animals
 Bacteria
Herpes mouth virus:
Chicken Pox
& Polio Virus
Rabies virus
Hepatitis B (Liver)
Cow pox vaccination 1749



Acquired
Immunization
Artificial
injection of a
small amount
of virus
Body’s immune
response
makes
antibodies
Lytic Cycle (Replication) of a
Virus - “AVIRAL”
1. Adsorption of virus
onto the host
3. Replication of
Viral DNA
4. Assembly of
protein coat
2. Insertion of
Virus DNA
into host cell
5.Lysis of
Host cell
Membrane
& release
Of virus
Viral Replication:
HIV virus structure:
HIV Virus
HIV virus infects T-cells


HIV virus
Weakens the
immune
system
AIDS patients
die of
“common”
diseases
when T cell
(WBC) count
falls
AIDS = break down of the immune
system & death due to common
diseases versus death by AIDS virus
Transduction:
Viral DNA becomes inserted
Into the Bacteria DNA
(1/100,000)
Genetic Engineering of Insulin
Restriction Enzymes:Made by some Bacteria
