Griffith

In his work with pneumonia-causing bacteria and mice, Griffith found that

• the protein coat from S cells transformed R cells
• Heat killed S cells caused pneumonia
• a substance from S cells transformed R cells
• bacteriophages injected DNA into bacteria

What was the most important concept demonstrated by Griffith's experiment?

• Dead bacteria donated something to living bacteria
• Heat destroys the ability of the bacteria to kill the mouse
• Proteins are the primary source of genetic information
