Question

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 1

The Correct Option is A

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.
