Chase was Dr. Hershey's lab technician in 1952. They tagged the protein coat
of phages with 35S and the DNA core
with 32P. Using a Waring
blendor (photo) they caused viruses to break
off outside of bacteria with tagged protein going to supernatant and label
DNA was lodged inside viral sediment layer confirming that DNA was the
genetic information of cells.
