WitrynaHershey and Chase used _____ to radioactively label the T2 phage's proteins. 35S. After allowing phages grown with bacteria in a medium that contained 32P and 35S, Hershey and Chase used a centrifuge to separate the phage ghosts from the infected cell. They then examined the infected cells and found that they contained _____, … Hershey and Chase showed that the introduction of deoxyribonuclease (referred to as DNase), an enzyme that breaks down DNA, into a solution containing the labeled bacteriophages did not introduce any 32 P into the solution. This demonstrated that the phage is resistant to the enzyme while intact.
