If DNA contained sulphur instead of phosphorus and proteins contained phosphorus instead of sulfur, what would have been the outcome of Hershey and Chase experiment?

Options

  1. ANo radioactive sulfur in bacterial cells
  2. BBoth radioactive sulfur and phosphorus in bacterial cells
  3. CRadioactive sulfur in bacterial cells
  4. DRadioactive phosphorus in bacterial cells

Correct answer

C. Radioactive sulfur in bacterial cells

Step-by-step solution

If Sulphur and Phosphorus change their presence in DNA and protein respectively the result of Hershey and Chase experiment will be reversed. Bacteria with radioactive sulphur formed at the base of Test Tube.
