What did Oswald avery discover
1 answer
Oswald Avery discovered that DNA is the substance responsible for genetic information transfer in bacteria. He conducted a series of experiments with his colleagues Colin MacLeod and Maclyn McCarty, which demonstrated that DNA, not proteins, was responsible for transmitting genetic information between bacteria. This discovery laid the foundation for the field of molecular genetics and paved the way for the study of DNA as the hereditary material in all organisms.
