Transformation
Something changed the IIR strain to the IIIS strain. What was it?
Transformation is the process of changing one form of bacteria into another form
trading genetic information
Between dead (HKIIIS) and living IIR

10. Griffith’s experiment

Transformation

11. Historical Perspective

Historical Perspective
Genetic material
Believed to be protein
More complex than nucleic acids
More common than nucleic acids

12. Avery and Co. McCarty & MacLeod
5/31/2019
Avery and Co. McCarty & MacLeod
took Griffith’s experiment one step farther
found out what had caused transformation
Used enzymes to breakdown organic molecules - Carbohydrase, Protease, Ribonuclease, and Deoxyribonuclease

13. Avery’s conclusion What’s the conclusion?
5/31/2019
Avery’s conclusion
Lipase didn’t block transformation
Carbohydrase didn’t block transformation
Protease didn’t block Transformation
Ribonuclease didn’t block transformation
Deoxyribonuclease blocked transformation
What’s the conclusion?
DNA is the genetic material of bacteria
