CHECK ALL THE APPLY. Choose all options that best completes the statement or
answers the question.
1) Without bacteria,
A) adequate amounts of carbon would not be available to living organisms.
B) plants would not be able to grow due to lack of nitrogen.
C) bioremediation would have limited use as a tool to clean up pollutants.
D) there would be an increase in decomposer organisms since the bacteria would no
longer be competing with fungi.
E) it would be easier to grow legumes like soybean, clover, and alfalfa plants.
2) Which of the following events would necessitate labelling a virus as emerging?
A) A virus is occurring for the first time in human populations.
B) A virus is rapidly increasing in its incidence (or frequency) in humans.
C) A virus is entering into new geographic regions.
D) A virus that previously infected bats is now found to be infecting mice.
E) A new bacteriophage is identified.
MULTIPLE CHOICE - Choose the one alternative that best completes the statement or
answers the question.

5) Which of the following does NOT directly provide support for the endosymbiotic
hypothesis?
A) Mitochondria and chloroplasts are surrounded by double membranes.
B) Mitochondria and chloroplasts have their own genomes.
C) Mitochondria and chloroplasts can synthesize proteins.
D) Mitochondria and chloroplasts contain genes that are strikingly similar to bacterial
genes.
E) Mitochondria and chloroplasts are both organelles involved in ATP production.
6) Which of the following is a characteristic only found in some viruses?
A) an inner core of nucleic acid
B) a protein capsid
C) is an obligate intracellular parasite
D) an envelope
E) genomes consisting of either DNA or RNA
7) A virus is specific to a particular type of host cell because
A) only certain hosts enter the environment inhabited by the virus.
B) not every virus contains metabolic machinery which can replace that of the host cell.
C) a spike or portion of the viral capsid is a specific match to a receptor on the surface of
a compatible host cell.
D) a host cell must be malfunctioning, or a virus cannot infect it.
E) the genome of the virus must be similar to that of its potential host.
8) Which is the correct order of events in the lytic cycle of a bacteriophage?
A) attachment - penetration - biosynthesis - maturation - release
B) integration - penetration - biosynthesis - maturation - release
C) attachment - integration - biosynthesis - maturation - release
D) attachment - biosynthesis - maturation - release
E) penetration - attachment - biosynthesis - release - maturation
9) A researcher infects a bacterium with a bacteriophage and notices that the infection does not
immediately bring about the destruction of the host cell. Instead, the phage's genetic material
is copied whenever the host reproduces. Which viral replication cycle is described here?
A) integration cycle
B) lysogenic cycle
C) biosynthetic cycle
D) lytic cycle
E) emergence cycle

10) Citrus tristeza virus (CTV) damages and kills susceptible citrus trees around the world. It can

A) use of insecticides to control the aphids
B) destruction of infected plants
C) production of transgenic citrus trees using genes that confer resistance to CTV
D) quarantine of fields with infected plants
E) application of antibiotic drugs to citrus plants
11) Animal viruses that have an envelope enter cells by
A) injecting their nucleic acid into the cell's cytoplasm.
B) fusing with the plasma membrane.
C) endocytosis.
D) plasmolysis.
E) either fusing with the plasma membrane or endocytosis.
12) Retroviruses
A) contain DNA.
B) contain the enzyme reverse transcriptase.

exposed individuals. Which of the means listed is likely to be the most effective?
A) blocking enzyme action
B) destroying the viral genome
C) dissolving the capsid
D) preventing conjugation
E) disrupting the viral envelope
