Frederic Griffith discovered transformation in his experiments on mice and Pneumococcus bacteria. He injected the mice with combinations of harmless, R-strain bacteria and disease-causing S-strain bacteria. Which combination of bacteria killed the mice and showed that transformation occurred?
heat-killed R-strain and live S-strain
heat-killed S-strain and live R-strain
heat-killed bacteria of both strains
live bacteria of both strains

Scientists wanted to learn more about Griffith’s experiment. They extracted a mixture of various molecules from the heat-killed bacteria. They found that ________ no longer occurred when they treated the mixture with enzymes that destroyed (carbohydrates / proteins / RNA / DNA / lipids). This experiment supports the hypothesis that (carbohydrates / proteins / RNA / lipids / DNA) is the genetic material.
translation
transcription
transformation
