In Hershey and Chase experiment, some viruses grew on medium that contained:
A
35S,32P
B
36S,34P
C
32S,36P
D
34S,36P
Answer
35S,32P
Explanation
Solution
In the Hershey and Chase experiment, 35S was used to label the protein coat of the bacteriophage, while 32P was used to label its DNA. This experiment demonstrated that DNA, not protein, is the genetic material, as only the 32P-labeled DNA entered the bacterial cells, while the 35S-labeled protein remained outside.
