Oswald Theodore Avery Jr. (October 21, 1877 – February 20, 1955) was a Canadian-American physician and medical researcher. The major part of his career was spent at the Rockefeller Hospital in New York City.
Oswald Avery was a Canadian-born American bacteriologist whose research helped ascertain that DNA is the substance responsible for heredity, thus laying the foundation for the new science of molecular genetics.
Oswald Avery led the team that discovered DNA passes heredity instructions through successive generations of organisms – it carries the chemical code of life. Avery and his colleagues published their discovery in a classic paper describing what came to be known as the Avery–MacLeod–McCarty experiment.
Learn how Oswald Avery and his colleagues identified the transforming principle in bacteria, which turned out to be DNA, and how Alfred Hershey and Martha Chase confirmed its role as the genetic material. Explore the classic experiments that led to the discovery of DNA structure and function.
Learn about the life and work of Oswald Avery, the bacteriologist who discovered that DNA is the transforming principle. Find out how he contributed to the field of molecular biology and why he did not win a Nobel Prize.
Oswald Avery (c.1930) In a very simple experiment, Oswald Avery's group showed that DNA was the "transforming principle." When isolated from one strain of bacteria, DNA was able to transform another strain and confer characteristics onto that second strain. DNA was carrying hereditary information.
Jan 20, 2014 · Oswald Avery, DNA, and the transformation of biology. Summary. Seventy years ago, Oswald Avery and his colleagues from the Rockefeller Institute published the first evidence that genes are made of DNA. Their discovery was received with a mixture of enthusiasm, suspicion and perplexity.
