Question

read each of the sentences that describe the results of the hershey - chase experiment. drag each statement to the correct bacteriophage experiment.
bacteriophage labeled with phosphorus - 32
bacteriophage labeled with sulfur - 35
bacteriophage contains radioactive isotope that is used to mark protein.
bacteriophage contains radioactive isotope that is used to mark dna.
radioactivity is found inside the infected bacterium.
no radioactivity is found inside the infected bacterium.
results confirm that dna is the genetic material of the bacteriophage.
results confirm that protein is not the genetic material of the bacteriophage.
bacteriophage marked with phosphorus - 32
bacteriophage marked with sulfur - 35

Explanation:

Phosphorus-32 labels DNA (DNA has phosphorus, proteins do not), so radioactivity from this isotope enters infected bacteria, confirming DNA is genetic material. Sulfur-35 labels proteins (proteins have sulfur, DNA does not), so no radioactivity from this isotope enters bacteria, confirming protein is not genetic material.

Answer:

Bacteriophage labeled with phosphorus-32:

1. Bacteriophage contains radioactive isotope that is used to mark DNA.
2. Radioactivity is found inside the infected bacterium.
3. Results confirm that DNA is the genetic material of the bacteriophage

Bacteriophage labeled with sulfur-35:

1. Bacteriophage contains radioactive isotope that is used to mark protein.
2. No radioactivity is found inside the infected bacterium.
3. Results confirm that protein is not the genetic material of the bacteriophage
