Your Answer
C
45P and 48S
Your Answer
D
24P and 27S

Solution

The correct option is A 32P and 35S
Radioactive elements 32P and 35S were used in Hershey and Chase’s experiments. Phosphorus and sulphur form important constituents of DNA (phosphorus) and certain amino acids (sulphur). Moreover, using the radioactive isotopes of these elements made it easier to trace them during the course of the experiment.
