In order to determine the genetic material of a T2 phage, Alfred Hershey and
Martha Chase conducted experiments using T2 phages that infected bacteria. In
one treatment, they grew phages with radioactive sulfur. In another treatment,
they grew phages with radioactive phosphorous. They allowed both types of
phages to infect bacterial cells. After infection, they found that only bacteria
infected with phages grown with radioactive phosphorous showed any
radioactivity. Why did they use radioactive sulfur and phosphorous for this
