The **Hershey-Chase** experiment (1952) used:
AMice and pneumonia bacteria
BBacteriophages with radioactive ³²P (DNA) and ³⁵S (protein)
CDrosophila melanogaster
DGarden pea plants
Answer & Solution
Correct answer: B. Bacteriophages with radioactive ³²P (DNA) and ³⁵S (protein)
Hershey and Chase used bacteriophages labelled with ³²P (DNA) or ³⁵S (protein coat) to infect *E. coli*. Only ³²P entered the cells — proving DNA, not protein, is the genetic material.
