Question

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.
E)bacteriophages injected DNA into bacteria.

Accepted Answer

Griffith's experiments demonstrated that some substance from the pathogenic bacteria (later found to be DNA) was transferred to the nonpathogenic bacteria, causing them to become pathogenic. This process is now known as transformation.
