1. Frederick Griffith

2. Griffith’s Achievement Discovered that bacteria goes through transformation. Set grounds for later discoveries having to do with bacteria.

3. Griffith’s Research Frederick Griffith’s research showed that dead bacteria could still pass on their disease causing DNA to harmless bacteria. He called this transformation.

4. Griffith’s Experiment

5. Possible Mistakes Oswald Avery thought that Griffith had conducted his experiments without a definite control group. Avery also believed that Griffith’s experiment was conducted poorly and there was a chance the mice had died from contamination instead of the bacteria.

6. Who It Helped Griffith’s discovery later helped out in the Avery-MacLeod experiment on how DNA is the substance that causes bacteria transformation. Watson and Crick later went off Griffith’s work in their 1953 paper telling of DNA’s molecular structure.
