BIO 212 Exam 3 (Missouri State University
Microbiology) Questions and Answers 100%
Solved
Where in the cell do different viruses replicate? RNA viruses replicate in the cytoplasm,
DNA viruses require a nucleus
What determines a viruses host range? A virus can invade its host cell only through
making an exact fit with a specific host molecule
What is CPE? A cytopathic effect. It refers to the damage that viruses can cause to host
cells during replication
What is the association between viruses and cancer? Some viruses like hepatitis B and
hepatitis C have been linked to an increased risk of certain cancers. AKA transforming infections
What is a bacteriophage? A virus that infects bacteria. Phage = eat
How are viruses grown and studied? in vivo: viral cultivation in lab animals or embryonic
bird tissues, living
, BIO 212 Exam 3 (Missouri State University
Microbiology) Questions and Answers 100%
Solved
in vitro: viral cultivation in cell or tissue culture, petri dish
What is the difference between lysogenic and lytic cycles? The lysogenic cycle involves
the virus integrating its genetic material into the host cell's genome, the lytic cycle involves the
destruction of the host cell
What are viroids? small circular RNA molecules that infect plants
What are prions? misfolded versions of normal protein that can cause disease
What are satellite viruses? Viruses dependent on other viruses for replication
What is positive, single-strand RNA virus? RNA genomes that are ready for immediate
translation into proteins. Example: Poliovirus

Microbiology) Questions and Answers 100%
Solved
Are all interactions between humans and microbes bad? No, many microbes live in or on
our bodies and provide benefits like acting as a skin barrier and promoting a healthy digestive
system.
How do microbes help us? Aiding in digestion, producing vitamins and training our
immune system to recognize harmful pathogens.
Colonization Presence of microorganisms in or on the body without causing harm.
Infection When a pathogenic microbe invades and causes damage to the host's tissue
Disease The clinical manifestation of an infection, characterized by symptoms of fever,
pain, and inflammation
Where are normal microbiota found in humans? Can be found on skin, in oral cavity,
nasal cavity, respiratory tract, G.I. tract, and genitourinary tact.
