The Avery–MacLeod–McCarty experiment showed that DNA was the transforming agent observed in Griffith's experiment.

Griffith's experiment (1928) suggested that bacteria were capable of transferring genetic information (DNA) by a process of horizontal gene transfer called transformation.

While the bacteria were killed by heat, Frederick Griffith observed that the DNA had was taken up by II-R strain bacteria via transformation.

Avery–MacLeod–McCarty experiment observed that protease enzymes did not destroy the transforming agent (but DNAse destroyed this transforming principle), thereby suggesting that the transforming agent in Griffith's experiment was bacterial DNA.
