Which of the following could cause DNA from the main chromosome of a
donor cell to be incorporated into the main chromosome of the recipient
cell?
conjugation between two F- cells
conjugation between an Hfr cell and an F- cell
conjugation between an F+ cell and an F- cell
conjugation between two F+ cells - CORRECT ANSWER-conjugation between
an Hfr cell and an F- cell
Suppose conjugation occurs between an Hfr cell and an F- cell. Although
not typical, what would have to occur for the recipient cell to become an Hfr
cell?
A portion of the F plasmid would have to be transferred to the recipient cell.
The entire F factor would have to be incorporated into the recipient cell's
chromosome.
,A portion of the F factor would have to be incorporated into the recipient
cell's chromosome.
The entire F factor would have to be transferred to the recipient cell. -
CORRECT ANSWER-The entire F factor would have to be incorporated into the
recipient cell's chromosome.
How does the large amount of genetic variation observed in prokaryotes
arise? See Concept 27.2 (Page 576)
View Available Hint(s)
The mutation rate in prokaryotes is much higher than in eukaryotes.
They have extremely short generation times and large populations.
They can exchange DNA with many types of prokaryotes by way of
horizontal gene transfer.
They have a relatively small genome.
The second and third answers are correct. - CORRECT ANSWER-The second
and third answers are correct.
Genes for the resistance of antibiotics are usually located __________.
See Concept 27.2 (Page 576)
View Available Hint(s)
in eukaryotic cells
on the outside of the cell wall
on plasmids
on the main chromosome
,in mitochondria - CORRECT ANSWER-on plasmids
If a bacterium regenerates from an endospore that did not possess any of
the plasmids that were contained in its original parent cell, the regenerated
bacterium will probably also lack ________.
a cell wall
water in its cytoplasm
a chromosome
antibiotic-resistant genes - CORRECT ANSWER-antibiotic-resistant genes
What process is occurring at Time C that is decreasing the DNA content?
degradation of DNA that was not retained in the recipient's chromosome
reversal of the direction of conjugation
cytokinesis
crossing over - CORRECT ANSWER-degradation of DNA that was not retained
in the recipient's chromosome
In a hypothetical situation, the genes for sex pilus construction and for
tetracycline resistance are located on the same plasmid within a particular
bacterium. If this bacterium readily performs conjugation involving a copy
of this plasmid, then the result should be the _____.
subsequent loss of tetracycline resistance from this bacterium
production of endospores among the bacterium's progeny
, rapid spread of tetracycline resistance to other bacteria in that habitat
temporary possession by this bacterium of a completely diploid genome -
CORRECT ANSWER-rapid spread of tetracycline resistance to other bacteria in
that habitat
Which of the following is LEAST associated with the others?
conjugation
horizontal gene transfer
transformation
binary fission - CORRECT ANSWER-binary fission
Sexual reproduction in eukaryotes increases genetic variation. In
prokaryotes, transformation, transduction, and conjugation are
mechanisms that increase genetic variation. A fundamental difference
between the generations of genetic variation in the two domains is:
A. Crossing over is a major mechanism in creating genetic variation in
prokaryotes while independent assortment is a major mechanism is
eukaryotes.
B. Eukaryotic variation occurs primarily within a single generation while
prokaryotic variation occurs over many generations.
C. Eukaryotic genetic variation occurs with vertical gene transfer while
prokaryotic genetic variation occurs with horizontal gene transfer.
D. Eukaryotes are able to generate mutations in response to environmental
stress while prokaryotes only generate random variation. - CORRECT ANSWER-
Eukaryotic genetic variation occurs with vertical gene transfer while
prokaryotic genetic variation occurs with horizontal gene transfer.
