• ANSWER: The disintegration of a cell by
disruption of the plasma membrane.
• QUESTION: Lysis
Answer
Question
A-200
• ANSWER: A disease that is caused by
new or reappearing infectious agents
that typically exist in animal populations.
• QUESTION: Emerging Disease
Answer
Question
A-300
• ANSWER: A method of viral replication
that results in the destruction of a host
cell and the release of many new virus
particles.
• QUESTION: Lytic Cycle
Answer
Question
A-400
• ANSWER: A membranelike layer that
covers the capsids of some viruses.
• QUESTION: Envelope
Answer
Question
A-500
• ANSWER: Viral DNA that has attached
to a host cell’s chromosome and that is
replicated with the chromosome’s DNA.
• QUESTION: Provirus
Answer
Question
B-100
• ANSWER: A gene that induces cancer,
or uncontrolled cell proliferation.
• QUESTION: Oncogene
Answer
Question
B-200
• ANSWER: A weakened form of a virus
that cannot cause a disease.
• QUESTION: Attenuated Virus
Answer
Question
B-300
• ANSWER: The viral genome (DNA) of
a bacteriophage that has entered a
bacterial cell, has become attached to
the bacterial chromosome, and is
replicated with the host bacterium’s
DNA.
• QUESTION: Prophage
Answer
Question
B-400
• ANSWER: A protein sheath that
surrounds the nucleic acid core in a
virus.
• QUESTION: Capsid
Answer
Question
B-500
• ANSWER: A virus that contains
singlestranded RNA and produces a
reverse transcriptase, which converts
RNA to DNA.
• QUESTION: Retrovirus
Answer
Question
C-100
• ANSWER: An infectious agent that is
made up of a short, circular, single
strand of RNA that does not have a
capsid; the smallest known particle that
is able to replicate.
• QUESTION: Viroid
Answer
Question
C-200
• ANSWER: Describes a microorganism
that causes disease and that is highly
infectious; strictly, refers only to viruses
that reproduce by the lytic cycle.
• QUESTION: Virulent
Answer
Question
C-300
• ANSWER: An infectious particle that
consists only of a protein and that does
not contain DNA or RNA.
• QUESTION: Prion
Answer
Question
C-400
• ANSWER: A gene that regulates
normal cell division but that can become
a cancer-causing oncogene as a result
of mutation or recombination.
• QUESTION: Proto-Oncogene
Answer
Question
C-500
• ANSWER: A virus whose replication
includes the lysogenic cycle.
• QUESTION: Temperate Virus
Answer
Question
D-100
• ANSWER: In biology, any agent, such as a
plasmid or a virus, that can incorporate
foreign DNA and transfer that DNA from one
organism to another; an intermediate host
that transfers a pathogen or a parasite to
another organism.
• QUESTION: Vector
Answer
Question
D-200
• ANSWER: A method of viral replication
in which a viral genome is replicated as
a provirus without destroying the host
cell.
• QUESTION: Lysogenic Cycle
Answer
Question
D-300
• ANSWER: A virus that is not able to
replicate in a host.
• QUESTION: Inactivated Virus
Answer
Question
D-400
• ANSWER: A nonliving, infectious
particle composed of a nucleic acid and
a protein coat; it can invade and destroy
a cell.
• QUESTION: Virus
Answer
Question
D-500
• ANSWER: A virus that infects bacteria.
• QUESTION: Bacteriophage
Answer
Question
FINAL JEOPARDY

the synthesis of new viral capsid and
that is used to treat diseases such as
AIDS.
