Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic strain can convert some of the living cells into the pathogenic form.
This experiment was conducted by Frederick Griffith in 1928. He observed that when he mixed a harmless strain of bacteria with a heat-killed virulent strain, the harmless bacteria were transformed into a virulent form. This led to the hypothesis that something in the heat-killed bacteria had transformed the live bacteria.
It is necessary to autoclave transformed cells immediately after the experiment to prevent their unintentional release into the environment, where they could potentially reproduce and propagate. Autoclaving helps to ensure proper containment and disposal of genetically modified organisms, reducing the risk of unintended environmental impact.
