Question

In their classic experiment to establish the nature of the genetic material, Alfred Hershey and Martha Chase utilized radioactive isotopes of phosphorus ( ³² P ) and sulfur ( ³⁵ S ). What was the fundamental biochemical rationale for selecting these specific isotopes?

Quantrex Academy · Accepted Answer

Correct answer: C. DNA contains phosphorus but lacks sulfur, whereas proteins contain sulfur but lack phosphorus.

Alfred Hershey and Martha Chase grew some viruses on a medium that contained radioactive phosphorus and some others on a medium that contained radioactive sulfur. Viruses grown in the presence of radioactive phosphorus contained radioactive DNA but not radioactive protein because DNA contains phosphorus but protein does not. Similarly, viruses grown on radioactive sulfur contained radioactive protein but not radioactive DNA because proteins contain sulfur (in specific amino acids) but DNA does not. This distinct bi
