True or False: Horizontal gene transfer may play a role in the
evolution of prokaryotes (e.g., in the spread of bacterial
antibiotic resistance), but does not play a role in the evolution
of eukaryotes (e.g., in humans).
What is horizontal gene transfer?
What are the three different types of horizontal gene
transfer?
What sets transformation apart from the other types of
horizontal gene transfer?
Respond to the items below.
Explain the role of horizontal gene transfer (conjugation,
transformation, and transduction) in contributing to the spread of
drug resistant microbes.
Describe the four common mechanisms of antimicrobial drug
resistance used by bacteria and give an example of each.
Will developing new antibiotics stop the problem of drug
resistant microbes? How high of a priority is this for the
scientific research community?
(a) Microorganisms play a role in the formation of hardness in
groundwater. True or false? Explain.
(b) In the United States, chlorine is preferred as a disinfectant
over ozone because it has a residual. Why is the presence of a
residual important? In recent years ozone has been replacing
chlorine as the primary disinfectant in the United States. What are
the advantages and disadvantages of this?
Horizontal gene transfer (how does this differ from
vertical gene transfer?)
a. Transformation (pre-existing variations
in a population)
