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.
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?
