Chapter 16: 16-1TYU (page 333)
In his work with pneumonia-causing bacteria and mice, Griffith found that
- the protein coat from pathogenic cells was able to transform non-pathogenic cells.
- heat-killed pathogenic cells caused pneumonia.
- some substances from pathogenic cells were transferred to non-pathogenic cells, making them pathogenic.
- the polysaccharide coat of bacteria caused pneumonia.
