1944 - Journal of Experimental Medicine. Paper suggests that __________ rather than __________ may be the hereditary material of bacteria - and perhaps higher organisms as well.
Understand the Problem
The question appears to refer to a historical study from the Journal of Experimental Medicine related to the hereditary material of bacteria. It likely asks to fill in the blanks regarding the substance that serves as hereditary material.
Answer
DNA rather than protein
The final answer is DNA rather than protein.
Answer for screen readers
The final answer is DNA rather than protein.
More Information
In the pivotal 1944 paper by Oswald Avery, Colin MacLeod, and Maclyn McCarty, they provided experimental evidence that DNA, not protein, is the hereditary material in bacteria. This shifted the scientific understanding of genetic material, impacting the study of genetics profoundly.
Tips
A common mistake is assuming proteins were always known not to be genetic material. Earlier, proteins were thought to be the carriers due to their complexity.
