Answer
• Contains DNA and can make proteins but
contains no membrane-bound organelles.
Question
• What are bacteria?
Answer
• Consists of a nucleic acid usually
surrounded by a protein coat.
Question
• What is a virus?
Answer
• Made of protein only.
Question
• What is a prion?
Answer
• Secretes enzymes and digests food outside
its cells. We eat the fruiting bodies of some
species.
Question
• What are fungi?
Answer
• Single-celled eukaryotes. Members of this
group do not easily fit into other kingdoms.
Question
• What are protists?
Answer
• Responsible for rising bread and brewing
beer.
Question
• What is yeast?

earth.

Question
• What is cyanobacteria?
Answer
• Responsible for the production of vitamin K
in the human colon.
Question
• What is bacteria (E. coli)?
Answer
• Exists in a symbiotic relationship with coral
performing photosynthesis. Damaged when
coral reefs are “bleached.”
Question
• What are algae?
Answer
• Role that bacteria play in the nodules of
some plants which provides an essential
nutrient.
Question
• What is nitrogen fixation?
Answer
• Three cell shapes used to distinguish
bacteria.
Question
• What are round (cocci), rod (bacillus), and
spiral (spirochete)?
Answer
• Stain used to distinguish bacterial cell wall
structures.
Question
• What is gram stain?
Answer
• Structure responsible for movement in
bacteria.
Question
• What is a flagellum?
Answer
• Tube through which “male” DNA is
transferred to a “female” strain in
conjugation.
Question
• What is a pilus?
Answer
• Bacterial structure which aids in survival in
adverse conditions.
Question
• What is an endospore?
Answer
• Caused by a protist and spread by
mosquitoes. Sickle cell carriers are less
likely to contract this deadly disease.
Question
• What is malaria?
Answer
• Spread by deer ticks and is named after a
town in Connecticut.
Question
• What is Lyme disease.
• Can be carried on improperly cleaned
uncooked food and causes illness in humans
(and sometimes death). Recent cases linked
to eating raw tomatoes and/or hot peppers.
Question
• What is E. coli O157;H7
Answer
• Disease that causes the most deaths worldwide. Spread through the air through
coughing.
Question
• What is Tuberculosis?
Answer
• Scientists used to think this stomach disease
was caused by stress. Recently discovered
that it is caused by a bacterium, H. pylori.
Question
• What are ulcers?
Answer
• The causative agent for AIDS.
Question
• What is HIV?
Answer
• The name for transfer of DNA between
bacteria.
Question
• What is horizontal gene transfer (HGT:
transformation, conjugation, or
transduction)?
Answer
• Disease that can be caused by eating
improperly canned food. Disease is caused
by a toxin made by the bacteria. Injection
of this toxin is used to remove wrinkles.
Question
• What is botulism?
Answer
• Process where naked DNA is transferred
into a bacterium. This method is used to
make recombinant DNA clones.
Question
• What is transformation?
Answer
• Cause of concern in hospital bacterial
infections.
Question
• Multiple Drug Resistant bacteria.
