Question

How Griffith's experiment helps in the identification of DNA as the genetic material.

Answer 1

Alfred Hershey & Martha Chase. Much earlier, scientists believed that thegenetic material was protein. In 1952, Hershey & Chase were the ones to conclusively prove that DNA is thegenetic material. They worked with bacteriophages – viruses that infect bacteria.

Answer 2

In 1928, Fred Griffith performed an experiment that provided a foundation for the discovery that DNA is the genetic material. He was studying the pathogenicity of Streptococcus pneumoniae . This bacteria causes a form of pneumonia in humans. He was not particularly interested in the genetic material debate.
