WebIn 1952, scientist Alfred Hershey and Martha Chase did a series of experiments to help confirm that DNA is the genetic material. Before this experiment, many scientists still used to think that proteins are the genetic material. WebHershey and Chase did two experiments to prove that DNA is the carrier of the genetic information. First, they grew phages (viruses which infect bacteria) in a medium containing radioactive sulphur (35 S). This marked all the proteins of the phage (the hull) radioactive. They then used this phage to infect bacteria.
