How was bacterial transformation discovered?

Bacterial transformation was discovered in 1928 by Frederick Griffith while studying Streptococcus pneumoniae. Griffith observed that heat-killed virulent bacteria could transfer their genetic material to live, non-virulent bacteria, transforming them into a virulent form. This experiment demonstrated the transfer of genetic information between bacterial cells, laying the groundwork for later discoveries identifying DNA as the hereditary material.
