Answer:
The 32P (phosphorus) was used in the Hershey-Chase experiment because phosphorus is present in deoxyribonucleic acid (DNA), but not in protein. Contrastingly, sulfur (S) is present in the amino acids cysteine and methionine. Hence, 35S was used to label only the proteins because DNA does not contain sulfur.
