WebHershey and Chase worked to discover whether it was a protein or DNA that entered the bacteria from virus. They labelled some phages with radioactive sulphur and the others with radioactive phosphorus. These radioactive phages were used to infect E. coli. Then, E.coli was blended and centrifuged to remove viral particles. WebThe first notable group of scientists that used radioactivity to an experimental advantage were Alfred Hershey and Martha Chase. In the 1950s, Hershey and Chase were trying to decipher if the DNA or proteins were the genetic material. To figure this out, they used T2 bacteriophage, a virus that infects E. coli.
