MCB 2610 Exam 1 - UConn
Microbiology - correct answer ✔The study of how microbes interact with
humans, with food, and how they can be used by humans


Microbes - correct answer ✔Forms of life too small to be seen with the naked
eye (Bacteria, fungi, algae, protists)


Types of microbial cells - correct answer ✔Prokaryotic & Eukaryotic cells


Prokaryotic cells - correct answer ✔Lack a true membrane-delimited nucleus
(not absolute)


Eukaryotic cells - correct answer ✔-Have a membrane-enclosed nucleus
-More complex morphologically (membrane-enclosed organelles)
-Usually larger


Classification schemes: Aristotle - correct answer ✔Two groups:
-Plants
-Animals


Classification schemes: Robert Whittaker (1969) - correct answer ✔Five
kingdom system: -Animalia
-Plantae
-Fungi
-Monera (included bacteria)
-Protista

,-Had not discovered archaea (included them in bacteria)


Classification schemes: Carl Woese et al (1990 paper) - correct answer
✔Three domain system: Advances in electron microscopy, biochemistry,
physiology, and ability to determine nucleic acid and protein sequences
-Based on a comparison of small subunit (SSU) ribosomal RNA gene
sequences
-Bacteria (true bacteria)
-Archaea: as different from bacteria as bacteria from eukarya -Eukarya


Bacteria: single-celled or multi-cellular? - correct answer ✔Usually single-
celled


Bacteria: cell walls? - correct answer ✔Majority have cell walls with
peptidoglycan


Bacteria: membrane-bound nucleus? Organelles? - correct answer ✔Most
lack


Bacteria: environment - correct answer ✔Ubiquitous: live in every
environment (some live in extreme environments)


An environment where there is no bacteria - correct answer ✔High-pressure,
high-temperature (used to sterilize)


Are bacteria good or bad? - correct answer ✔Some cause disease, but most
are beneficial (i.e. many recycle elements, such as Cyanobacteria)


Cyanobacteria & recycling of elements - correct answer ✔-Photosynthetic

,-Produce significant amounts of O2 (responsible for oxygen in our
environment)


Archaea: cell walls? - correct answer ✔Lack peptidoglycan in cell walls and
have unique membrane lipids


Archaea: metabolic characteristics - correct answer ✔Some have unusual
metabolic characteristics (i.e. methanogens: produce methane gas_


Archaea: environment - correct answer ✔Many live in extreme environments


Archaea: Role in causing diseases - correct answer ✔Unclear (mostly
beneficial)


Eukarya: Types - correct answer ✔-Plants
-Animals
-Algae (Photosynthetic)
-Protozoa (May be motile, "hunters, grazers")
-Slime molds
-Water molds
-Fungi


Slime molds: 2 life cycle stages - correct answer ✔-Mold-like
-Protozoan-like


Water molds - correct answer ✔-Protists that grow in moist environments
-Some cause devastating diseases in plants

, Fungi - correct answer ✔Primarily decomposers, some cause disease (e.g.
yeasts: unicellular; molds: multicellular)


Acellular infectious agents - correct answer ✔-Viruses
-Viroids and virusoids
-Prions


Why are acellular infectious agents not part of the 3 domain system - correct
answer ✔Based on rRNA sequences (rRNA analysis) & viruses do not have
ribosomes


If we discover forms of life on another planet, would studies of rRNA gene
sequences be useful for characterizing these life forms? - correct answer
✔NO: could be formed of something other than rRNA (could try it)


Smallest of all microbes - correct answer ✔Viruses


Virus compisiton - correct answer ✔-Very simple: some consist of only
proteins and nucleic acids
-DNA or RNA (not both)


Are viruses alive? - correct answer ✔Technically not


Viruses & their host cell - correct answer ✔-Requires host cell to replicate
-(Usually) have little to no biochemical activity outside of the host cell
-Inert and nonreactive outside of host cell
