What did oswald Avery do?
Oswald Theodore Avery (1877-1955) was a Canadian-born bacteriologist, research physician, and one of the founders of immunochemistry. He is best known for his discovery that deoxyribonucleic acid (DNA) serves as genetic material. His work helped create a platform for modern DNA research.

Thanks for the feedback!
Avery is attributed with the discovery that the material in which the genetic information is encoded is DNA and not protein or carbohydrate.
He determined that the DNA is most likely the genetic material and discovered pneumoccal transformation.
Discovered the double-helix(DNA)

Oswald Avery was diagnosed with liver cancer in 1954. He died on February 20th, 1955 from liver cancer. He was 77.
Oswald Avery in DNA Oswald Avery proved that DNA was the genetic material in organisms. He began his investigation after Griffith's experiment with transformation of DNA …in mice. Griffith exploited how non-pathogenic bacteria had the ability to transform into pathogenic bacteria by the presence of dead pathogenic bacteria. Avery took qualitative tests for protein in a sample of the transforming agent and the test came back negative, meaning the presence of the unknown genetic material does not exist. However, the qualitative test for DNA came back positive, confirming the genetic material's presence. Avery further proved his discovery by analyzing the chemical components of the genetic material, finding that the phosphorous-nitrogen ratio was closely similar to that of DNA.
YES!, in 1944.
They were three Scientists whom confirmed the active role of DNA in cell transformation.
