Overview
Griffith's experiment, conducted in 1928, was a groundbreaking study that demonstrated the phenomenon of bacterial transformation. By using two strains of Streptococcus pneumoniae, one virulent and one non-virulent, Griffith showed that the non-virulent strain could acquire virulence when exposed to...
