Hershey-Chase Experiment & DNA Proof — NEET Biology
📚 Practice ConceptHow did Hershey and Chase differentiate between DNA and protein in their experiment while proving that DNA is the genetic material?
Which of the following statements are correct regarding the Hershey and Chase experiment to prove DNA as the genetic material? S1: Viruses were grown in a medium containing radioactive sulfur (35S) to label viral DNA. S2: Viruses grown in the presence of radioactive phosphorus (32P) contained radioactive DNA but not radioactive protein. S3: After infection and blending, bacteria infected with 35S labeled viruses showed radioactivity in the supernatant, not in the bacterial cells. S4: The experiment demonstrated that protein from the viruses entered the bacterial cells during infection. S5: Centrifugation was used to separate the viral particles from the bacterial cells after infection.
