Question 15 of 25

What new knowledge was gained from Frederick Griffith's work with pneumococci bacteria?

A. Transforming principles exist only in bacteria.
B. Bacteria contain a physical substance that can change the structure of other bacteria.
C. The transforming principle in bacterial strains is carried by proteins.
D. Bacterial strains cannot change from one generation to the next.

Answer :

Final answer:

Frederick Griffith's work discovered the transforming principle in bacteria, which is a physical substance that can change the structure of other bacteria.

Explanation:

Frederick Griffith's work with pneumococci bacteria led to the discovery of the transforming principle, which is a physical substance in bacteria that can change the structure of other bacteria. The new knowledge gained from his work was that this transforming principle exists and can be passed from one bacterial strain to another, resulting in new traits being acquired by the recipient bacteria. This discovery was a significant milestone in the field of genetics and laid the foundation for the understanding of genetic transformation.
