Detailed explanation-1: -Frederick Griffith, (born October 3, 1877, Eccleston, Lancashire, England-died 1941, London), British bacteriologist whose 1928 experiment with bacterium was the first to reveal the “transforming principle, ” which led to the discovery that DNA acts as the carrier of genetic information.
Detailed explanation-2: -Griffith concluded that the R-strain bacteria must have taken up what he called a “transforming principle” from the heat-killed S bacteria, which allowed them to “transform” into smooth-coated bacteria and become virulent.
Detailed explanation-3: -Griffith concluded that living, non-virulent bacteria was transformed into virulent bacteria from the heat-killed virulent bacteria. Griffith published the results of this experiment in the Journal of Hygiene. His experiments with mice in 1928 are what led to his major discovery of bacterial transformation.
