Vedclass · Answer

(C) In the Hershey-Chase experiment (transduction experiment),radioactive isotopes were used to distinguish between protein and $DNA$ as genetic material.$1.$ Proteins contain sulfur but not phosphorus. Therefore,the bacteriophages were grown in a medium containing radioactive sulfur $(^{35}S)$ to label the protein coat.$2.$ $DNA$ contains phosphorus but not sulfur. Therefore,the bacteriophages were grown in a medium containing radioactive phosphorus $(^{32}P)$ to label the $DNA$.Thus,the correct isotopes for protein and $DNA$ are $^{35}S$ and $^{32}P$,respectively.

Which of the following radioactive isotopes were utilized for labeling protein and $DNA$ in the transduction experiment,respectively?
