Alfred Hershey and Martha Chase completed scientific experiments using a phage called T2 to prove that DNA is responsible for genetic code and hereditable information. They utilized a radioactive isotope of phosphorus to label DNA in one set, and a radioactive isotope of sulfur to mark protein. The two scientists intended on observing which one of the two parts of the T2 actually moved into an E. Coli cell throughout infection. All of the phages phosphorus is located in the DNA, so the atoms of the phosphorus ticketed only the DNA. The same thing happened with the protein and sulfur atoms. Nonradioactive cells were infected with both the protein marked and DNA marked batches. Hershey and Chase then proceeded with their research by examining
