Question

Quizplus · Accepted Answer

The experiment focused on the use of radioactively labeled phosphorus and sulfur to distinguish between DNA and protein as the genetic material. While DNA contains high amounts of phosphorous, it is not the only important element found in the nucleotides that make up DNA. Nitrogen is a key component of nucleotides in DNA, but it was not relevant to this specific experiment.
