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 (\(^{32}\text{P}\)) is used to label DNA (since DNA contains phosphorus and proteins do not). When the bacteriophage labeled with \(^{32}\text{P}\) infects the bacterium, the radioactivity is found inside the infected bacterium. This result confirms that DNA is the genetic material of the bacteriophage.
• Sulfur - 35 (\(^{35}\text{S}\)) is used to label protein (since proteins contain sulfur and DNA does not). When the bacteriophage labeled with \(^{35}\text{S}\) infects the bacterium, no radioactivity is found inside the infected bacterium. This result confirms that protein is not the genetic material of the bacteriophage.

Answer:

• Bacteriophage marked with phosphorus - 32: Bacteriophage contains radioactive isotope that is used to mark DNA; Radioactivity is found inside the infected bacterium; Results confirm that DNA is the genetic material of the bacteriophage.
• Bacteriophage marked with sulfur - 35: Bacteriophage contains radioactive isotope that is used to mark protein; No radioactivity is found inside the infected bacterium; Results confirm that protein is not the genetic material of the bacteriophage.
