This congress marked a shift in the party's leadership and strategy, as Mao's ideas began to gain influence.

The Griffith experiment, conducted by Frederick Griffith in 1928, was a groundbreaking study in the field of biology. Griffith was investigating the phenomenon of bacterial transformation, which is the ability of bacteria to transfer genetic material from one to another. He used two strains of the bacterium Streptococcus pneumoniae, one virulent and one non-virulent, and observed that the non-virulent strain could become virulent when exposed to heat-killed virulent bacteria. This led to the discovery of the transforming principle, which was later identified as DNA. The Griffith experiment provided crucial evidence for the role of DNA in genetic inheritance and laid the foundation for the field of molecular biology. **
