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

Question

Quizplus · Accepted Answer

Griffith's experiment demonstrated that a substance from dead pathogenic bacteria could transform live nonpathogenic bacteria into a pathogenic form. This transformation suggested that the genetic material could be transferred between bacteria, leading to the discovery of DNA as the material of heredity.
