Detailed explanation-1: -The “Griffith’s Experiment, ‘’ conducted in 1928 by English bacteriologist Frederick Griffith described the conversion of a non-pathogenic pneumococcal bacteria to a virulent strain. In this experiment, Griffith mixed the living non-virulent bacteria with a heat inactivated virulent form.

Detailed explanation-2: -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-3: -Frederick Griffith: Bacterial transformation. In 1928, British bacteriologist Frederick Griffith conducted a series of experiments using Streptococcus pneumoniae bacteria and mice.

Detailed explanation-4: -Experiment 4: Griffith mixed his heat-killed, disease-causing bacteria with live, harmless bacteria and injected the mixture into the mice. The mice developed pneumonia and died. Griffith concluded that the heat-killed bacteria passed their disease-causing ability to the harmless strain.
