in one singular sentance

Answer 1

Griffith conducted experiments using two strains of Streptococcus pneumoniae—one virulent and one non-virulent—by injecting mice with the live non-virulent strain and heat-killed virulent strain, ultimately demonstrating that the non-virulent bacteria could acquire virulence through transformation from the dead virulent bacteria, leading to pneumonia in the mice.
