If 100% of the DNA contents of a transducing bacteriophage were
DNA from the host chromosome, what would happen when the
bacteriophage infected a new bacterial cell?
Group of answer choices
The bacteriophage would be converted from a lysogenic phage to a
lytic bacteriophage.
The new bacterial cell would die.
No more bacteriophage would be synthesized, as there is no
bacteriophage genome available to direct synthesis.
More bacteriophage would be synthesized, resulting in death of the
new bacterial cell.
The new cell would lyse, immediately releasing infectious
particles
Homework Answers
Answer - No more bacteriophage would be synthesized, as there is no bacteriophage genome available to direct synthesis.
Explanation
During transduction, bacteriophage sometimes mistakenly packed bacteria chromosome as a genetic material. So, no bacteriophage DNA are present in this type of phages. Without its genes they not able to synthesize there head, tail etc, so it not produce new bacteriophage after infecting the bacteria.

The Hershey Chase experiment using radioactively labeled bacteriophage to infect bacteria proved that DNA was the genetic material. If you were reviewing those experimental results, which of the following would provide evidence that DNA was the genetic material? Select all that would apply. a) The DNA was localized in the cytoplasm of the bacterial cell, which is the same site that the bacterial chromosome is located. b) Radioactively labeled viral proteins were only found outside the cell and the viral...

The bacteriophage used in this experiment reproduces by the
lytic cycle. Suppose a similar experiment were conducted with a
bacteriophage that uses the lysogenic cycle. How would the effect
on the infected bacteria MOST likely differ?
A. The bacteriophage would attach to the bacteria and reproduce
in the extracellular space.
B. The bacteriophage would become permanently dormant and
unresponsive to environmental cues for reproduction.
C. The bacteriophage would attach its genes to the bacteria’s
DNA, allowing its genes to be...

Please classify each statement as describing transformation, conjugation, or transduction in bacteria. Bacteria can acquire plasmids from outside the cell. A bacterium that contains an F plasmid connects to a recipient bacterium that lacks an F plasmid with an appendage called a pilus, through which the plasmid is transferred. Some bacterial DNA fragments may be included when new phage particles are assembled. A cell can be treated to make it competent to take up DNA from its environment. When a...
