In the experiments of Griffith, the conversion of nonlethal R-strain bacteria to lethal S-strain bacteria

A) was due to genetic mutation.
B) was due to transformation.
C) proved that proteins are the genetic material.
D) could not be reproduced by other researchers.
E) was similar to experiments performed by Watson and Crick.

Griffith's Transformation

Griffith's transformation experiment demonstrated that bacteria can take up foreign DNA from their environment and express its genetic information, a foundational experiment in molecular biology.

R-strain Bacteria

A type of bacteria distinguished by its rough appearance due to the absence of a polysaccharide capsule, often used in studies of bacterial transformation.

S-strain Bacteria

A strain of bacteria that possesses a smooth capsule made of polysaccharides, making it virulent by protecting it from the host's immune system.
