Question
3. The result of the Hershey-Chase experiment was that radioactivity could be detected inside the bacterial cells when they were infected by bacteriophages marked with phosphorus-32. What did the investigators conclude from this result?
a. Bacteriophages inject their DNA into the bacterial cells.
b. Bacteriophages inject their protein into the bacterial cells.
Oc. Bacteriophages inject carbohydrates into the bacterial cells.
d. Bacteriophages absorb DNA from bacterial cells.
a. Bacteriophages inject their DNA into the bacterial cells.
b. Bacteriophages inject their protein into the bacterial cells.
Oc. Bacteriophages inject carbohydrates into the bacterial cells.
d. Bacteriophages absorb DNA from bacterial cells.

The correct conclusion from the result of the Hershey-Chase experiment is:
a. Bacteriophages inject their DNA into the bacterial cells.
In the experiment, the researchers used phosphorus-32 to label the DNA of the bacteriophage and found that it was the DNA, not the protein (labelled with sulfur-35), that entered the bacterial cells, indicating that DNA is the genetic material that is injected by bacteriophages.
