I think it is true not 100% sure but i believe it is true <span />
Frederick Griffith's discovery on the theory of genetics is credited to his experiment on mice. He subjected them to different strains of pneumonia bacteria. He concluded that there is an unidentified force that leads to the formation of different strains from what the mice were subjected to. This leads to the discovery of DNA, the carrier of traits. Scientist before did not know how the trait is passed on not until Griffith's experiment.
