Vedclass · Answer

(B) In the Hershey-Chase experiment,they used $T2$ bacteriophages to determine whether $DNA$ or protein is the genetic material.They grew some viruses in a medium containing radioactive phosphorus $(^{32}P)$ to label the $DNA$,as $DNA$ contains phosphorus but not sulfur.They grew other viruses in a medium containing radioactive sulfur $(^{35}S)$ to label the protein coat,as proteins contain sulfur but not phosphorus.When the viruses grown in the radioactive phosphorus $(^{32}P)$ medium infected the bacteria,the bacteria became radioactive because the viral $DNA$ (which was radioactive) entered the bacterial cells.Therefore,the correct medium is radioactive phosphorus.

In which medium were the viruses grown so that the infected bacteria became radioactive?
