Hershey and Chase performed an experiment in order to determine how bacteriophages infect bacteria. What did they find? The bacteriophage injects DNA into the host cell. This was found because, after centrifugation, the pellet was radioactive The largest difference between a Gram + and Gram - bacterial cell is: The gram + cell has a much thicker peptidoglycan layer Why does a Gram + cell stain blue/purple in a gram stain? The Gram + cell stains blue/purple because crystal violet rem...
