penetration of the host cell.
-Confers greater susceptibility to
disinfectants
-Is a flexible membrane composed of
protein and lipid
The viral envelope

viral components

-Is affected by base analogs in viral
inhibition
The viral genome -may be either DNA or RNA but not both

What is the A viroid is infectious RNA and a prion is
difference between infectious protein
a viroid and a
prion?
antigenic shift Major change in a viral surface
antigen that render antibodies made
against the previous version

Acute infection Illness characterized by signs and
symptoms that develop quickly but
last a relatively short time
Arbovirus Arthropod-borne virus; one of a large
group of RNA viruses carried by
insects and mites that act as
biological vectors
Bacteriophage A virus that infects bacteria; often
abbreviated to phage
Capsid Protein coat surrounding the nucleic acid
of a virus
Chronic infection Infection that develop slowly and persist
for months or years
Enveloped virus Characterized by a lipid bilayer
surrounding the nucleocapsid
A type of horizontal gene transfer
generalized occuring when a phage carries a
transduction random piece of bacterial DNA
acquired when a packaging error
occurs during the assembly of
phage particles
