GRIFFITH EXPERIMENT – 1928 Was trying to figure out how bacteria gave people ______

Answer 9

Answer 10

Transformation

Question 11

Griffith hypothesized that some _______-CONTAINING FACTOR was TRANSFERRED from the heat-killed harmful bacteria into the harmless live bacteria to make them able to kill the mice
