acyclovir
an antiviral drug
antiviral drug
drugs that interfere with viral nucleic acid synthesis
attenuated strain
refers to a preparation of a virus for a vaccine in which the
virus is incapable of causing disease under normal circumstances
azidothymidine (AZT)
an antiviral drug that inhibits the reverse transcriptase
of retroviruses, such as HIV
bacteriophage
a virus that infects bacteria
capsid
the protein covering a virus
envelope
a membrane-like structure outside the capsid that is made mostly of
lipids and taken from a host cell membrane during replication
glycoprotein
a molecule of protein with attached sugar chains
helix
a viral shape resembling a coiled spring
human immunodeficiency virus (HIV)
the virus that causes AIDS
icosahedron
a polyhedron or a capsid of a virus with 20 triangular faces
inactivated vaccine
a vaccine that has been treated so that its component
microorganisms no longer have the ability to cause disease
infectious disease
a disease caused by a pathogen that can be transmitted from
one individual to another
lysis
the disintegration of a cell by disruption of the plasma membrane
lysogenic cycle
a viral replication process that does not kill the host cell
immediately but stays inside the host for a long period of time
lytic cycle
the replication process of viruses that results in the destruction of
the host cell
obligate intracellular parasite
a parasite that requires a host cell in order to
reproduce
prion
a glycoprotein particle implicated in diseases with long incubation
periods
prophage
an intracellular bacteriophage that is harmless to the host cell
protease inhibitor
an antiviral drug that interferes with the synthesis of viral
capsids during viral replication; in combination with AZT has shown some
promise in treating patients infected with HIV
provirus
a viral DNA molecule produced by reverse transcriptase
receptor site
the area of a cell membrane where antigen attachment takes
place
retrovirus
a virus, such as HIV, that contains RNA and reverse
transcriptase
reverse transcriptase
an enzyme that makes DNA from an RNA
template
T cell
a thymus-derived lymphocyte that helps stimulate an immune response
against an antigen and can attack certain antigens
temperate
referring to a nonvirulent virus, rarely causing disease; moderate, not
subject to prolonged extremes of hot or cold
viroid
a short, single strand of RNA that causes disease in plants
temperate
referring to a nonvirulent virus, rarely causing disease; moderate, not
subject to prolonged extremes of hot or cold
virology
the study of viruses
virulent
disease-causing and highly infectious
virus
a nonliving infectious particle composed of a nucleic acid and a protein
coat
