How Did Frederick Griffith's Experiments Contributed To The Discovery Of DNA?

From 1928 to 1952, experiments done by Frederick Griffith, Oswald Avery, Alfred Hershey, and Martha Chase all did experiments that contributed to the discovery of the DNA. Frederick Griffith experiment was done in 1928, Oswald Avery’ was done during the early 1940’s, and Alfred Hershey’s with help from Martha Chase was done in 1952. All of these experiments contributed to the idea known as translation, the process of cell ribosomes converting proteins to messenger RNA, or mRNA. Because of how they helped with discovering translation, these three experiments help lead to the discovery of DNA. Before Frederick Griffith’s experiment, no one knew anything about DNA or what it was. Frederick Griffith studied two types of Pneumococcus bacteria,
