I.) Transmissible spongioform encephalopathy (TSE)
Animal viruses cause damage to the host cells (cytopathic effects), causing altered cell appearance and flawed physiology.
________ cause cancer by affecting the growth processes of the host cell.
Oncogenic effects cause cancer by affecting the growth processes of the host cell.
______ is a concept associated with bacterial viruses (bacteriophage); the virus integrates into the DNA of the bacterial chromosome and remains there without causing symptoms.
A.) Viroids B.) Virion
C.) Prions D.) Bacteriophage
E.) Lysis (lytic cycle) F.) Lysogeny (lysogenic cycle)
G.) Latency (latent infection) H.) Plaques
I.) Transmissible spongioform encephalopathy (TSE)
F.) Lysogeny (lysogenic cycle)
the virus integrates into the DNA of the bacterial chromosome and remains there without causing symptoms.
Latency = DNA animal viruses
Lysogeny = bacterial viruses (bacteriophages)
both are asymptomatic
Animal viruses cause damage to the host cells (cytopathic effects), causing altered cell appearance and flawed physiology.
_______ is a “reprogramming” of the cell.
Transformation is a “reprogramming” of the cell.
______ is a concept associated with DNA animal viruses; the virus integrates into the DNA of an animal cell and remains there without causing any symptoms.
A.) Viroids B.) Virion
C.) Prions D.) Bacteriophage
E.) Lysis (lytic cycle) F.) Lysogeny (lysogenic cycle)
G.) Latency (latent infection) H.) Plaques
I.) Transmissible spongioform encephalopathy (TSE)
G.) Latency (latent infection)
Latency = DNA animal viruses
Lysogeny = bacterial viruses (bacteriophages)
both are asymptomatic
______ is the term that describes when a virus is in its inactive form outside of the cell.
A.) Viroids B.) Virion
C.) Prions D.) Bacteriophage
E.) Lysis (lytic cycle) F.) Lysogeny (lysogenic cycle)
G.) Latency (latent infection) H.) Plaques
I.) Transmissible spongioform encephalopathy (TSE)

In the penetration phase of viral multiplication, ______ is when the virus is imported through the plasma membrane via a vacuole or vesicle and enzymes in the vacuole dissolve the evelope and capsid.
A.) direct penetration
B.) membrane fusion
C.) endocytosis
C.) endocytosis
When prions infect the brain, they cause ______ (clear spaces) that form within the brain, giving the brain a spongy appearnce.
