Vedclass · Answer

(C) The Hershey-Chase experiment $(1952)$ was designed to determine whether $DNA$ or protein is the genetic material.$1$. They grew some bacteriophages on a medium containing radioactive phosphorus $(^{32}P)$ to label their $DNA$,and others on a medium containing radioactive sulfur $(^{35}S)$ to label their protein coats.$2$. When the phages labelled with $^{35}S$ (protein) infected bacteria,the radioactivity remained in the supernatant after centrifugation,indicating that the protein did not enter the cell.$3$. When the phages labelled with $^{32}P$ $(DNA)$ infected bacteria,the radioactivity was detected inside the bacterial cells,proving that $DNA$ is the genetic material.$4$. Option $C$ correctly describes the result for the $^{35}S$ experiment: the radioactive protein coat remains outside the cell in the supernatant.

Recall the experiments done by Frederick Griffith,Avery,MacLeod,and McCarty,where $DNA$ was speculated to be the genetic material. If $RNA$,instead of $DNA$,was the genetic material,would the heat-killed strain of $Pneumococcus$ have transformed the $R$-strain into a virulent strain? Explain.
