In an experiment DNA from dead pathogenic bacteria was transferred into living bacteria that do not cause disease These altered bacteria were then injected into healthy mice These mice died of the?
The pathogenic DNA from the dead bacteria became active when combined with the DNA in the live bacteria. When injected into the mice, this reactivated DNA caused the disease and the mice died.
What would Hershy and Chase have concluded if both radioactive 32-P and 35-S were found in the bacteria in their experiment?
What result from griffith's experiment suggested that the cause of pneumonia was not a chemical poison released by the disease-causin bacteria?
What result from Griffiths experiment suggested that the cause of pneumonia wasnt a chemical poison?
Assuming you mean the Frederick Griffith bacterial experiment, the question left unanswered was how the rough strain (less harmful) bacteria transformed into the smooth strain (lethal) bacteria. When he injected live rough strain bacteria, the mouse lived. When he injected live smooth strain bacteria, the mouse died. But if dead smooth strain bacteria was injected, the mouse lived. So if either live rough strain or dead smooth strain could be injected without killing the mouse…
