Which scientist experimentally proved that DNA is the sole genetic material in bacteriophage?

Options

  1. ABeadle and Tatum
  2. BMeselson and Stahl
  3. CHershey and Chase
  4. DJacob and Monod

Correct answer

C. Hershey and Chase

Step-by-step solution

Alfred Hershey and Martha Chase (1952) experimentally proved that DNA is the sole genetic material in bacteriophage. On the other hand, Beadle and Tatum (1940s) experimentally showed one gene-one enzyme hypothesis using Neurospora. Meselson and Stahl first showed that DNA replicates semiconservatively through experiments on E.coli. Jacob and Monod were first to explain lac operon.
