Describe the hershey-chase experiment

WebThus, Hershey and Chase could determine whether DNA or proteins is the T2 genetic material by determining if either 35 S or 32 P is injected into a host E. coli cell during a bacteriophage infection. The Hershey and Chase experiment was done as follows (see figure 5.4): In one experiment, bacteriophage T2 proteins were labeled with 35 S. WebHershey and Chase employed this method to prepare both 32 P-labeled and 35 S-labeled bacteriophages, which they then used to infect bacteria. To determine which of the …
