Evidence that viral can program cells

Bacteriophages (phages) Bacteriophages (phages) are viruses that infect bacteria. Which of the viral component DNA-protein??

Experiment

Hershey and chase conclusion Hershey and chase concluded that the DNA of the virus is injected in the host cell during infection, leaving the protein outside . The injected DNA provides genetic information that make the cell produce new viral DNA and protein to make new viruses
