Question
chapter 13 lesson 1
identify the substance of the gene
reading tool
sequence of events

Griffith:
Avery:
Hershey-Chase:
Questions (1 short sentence each)
1) why was Griffith surprised when the mice injected with both harmless and heat-killed bacteria developed pneumonia and died
2) what does a bacteriophage inject into a bacterial call
3) what type of organism is a bacteriophage
bacteria, virus or eukaryote

### Graphic Organizer for Key Experiments
| Experiment | Key Findings and Importance |
|-------------------| ---------------------------------------------------------------------------- |
| **Griffith** | Showed that genetic material could be transferred between bacteria, revealing the concept of transformation. |
| **Avery** | Identified DNA as the substance responsible for transformation, providing evidence that DNA is the genetic material. |
| **Hershey-Chase** | Confirmed that DNA, not protein, is the genetic material in viruses, further solidifying the role of DNA in heredity. |
### Questions
1) Griffith was surprised because the harmless bacteria were transformed into deadly bacteria when mixed with heat-killed pathogenic bacteria, indicating that some substance from the dead bacteria was able to alter the living bacteria.
2) A bacteriophage injects its DNA (or RNA) into a bacterial cell.
3) A bacteriophage is a **virus**.
