WebQ- Summarise Avery's experiment in your own words. Ans- In 1944 Oswald Avery , Colin MacLeod, Maclin McCarty worked to determine the biochemical nature of 'transforming principle ' in Griffith's experiment. -They purified biochemicals (protein,DNA , RNA etc) from the heat killed S cells to see which of them transform live R cells into S cells. WebConcept 17 A gene is made of DNA. A gene is made of DNA. It's hard to imagine now the impact that Avery's experiments must have had. Until Avery's experiments, scientists weren't even sure that bacteria had genes. Avery's experiments showed that DNA is the tranforming principle, but he didn't try to figure out how transformation works.
