Vedclass · Answer

(A) Alfred Hershey and Martha Chase conducted experiments using bacteriophages to prove that $DNA$ is the genetic material.They grew some viruses on a medium that contained radioactive phosphorus $(^{32}P)$ and some on a medium that contained radioactive sulfur $(^{35}S)$.Viruses grown in the presence of radioactive phosphorus contained radioactive $DNA$ but not radioactive protein because $DNA$ contains phosphorus while protein does not.Similarly,viruses grown on radioactive sulfur contained radioactive protein but not radioactive $DNA$.When these radioactive bacteriophages were allowed to infect $E. coli$ bacteria,it was observed that only the radioactive $DNA$ entered the bacterial cells,while the radioactive protein remained outside.Thus,it was concluded that $DNA$ is the genetic material that is transferred from the virus to the bacteria.

In the Hershey and Chase experiment,what entered the bacteria from the virus?
