14. DNA Synthesis

The bacteria that Griffith experimented with were termed "R" and "S" bacteria because:

In his transformation experiments, what phenomenon did Griffith observe?

In his work with pneumonia-causing bacteria and mice, Griffith found that a. the protein coat from pathogenic cells was able to transform nonpathogenic cells. b. heat-killed pathogenic cells caused pneumonia. c. some substance from pathogenic cells was transferred to nonpathogenic cells, making them pathogenic. d. the polysaccharide coat of bacteria caused pneumonia.
