| Who proposed DNA as the hereditary material in the Central Dogma and what evidence did they have to back this up? |
|
Definition
In 1944, Avery and co took DNA from a dead S strain and injected it into an R strain, which then began to transform. They discovvered that the enzyme that degrades RNA and protein was not blocking the reaction, but the enzyme that degrades DNA was. They concluded that the physical and chemical properties of the transforming substance were similar to that of DNA. From this evidence they proposed that DNA was the hereditary material. |
