In the experiments conducted by Avery, McCarty, and MacLeod, which hypothetical result would indicate that protein, not nucleic
acid, was Griffith's transforming substance? Only the extracts from heat-killed cells treated with RNase are unable to transform nonvirulent bacteria into virulent bacteria. All of the extracts from heat-killed cells are able to transform nonvirulent bacteria. Only the extracts from heat-killed cells treated with D
Only the extracts from heat-killed cells treated with RNase are unable to transform nonvirulent bacteria into virulent bacteria.
Explanation:
The experiment by Avery, McCarty and MacLeod aimed to identify Griffith's "transforming principle," which is a principle that explains how transformation is a way of recombining, exchanging, or transferring genetic information between organisms or from one organism to another. For this, they used cell that were heat inactivated and purified the transforming principle of these cells.
The purified cells did not give positive results in the tests done by the scientists, but they presented transformants very similar to the DNA. However, Avery suspected that the result should be reinterpreted and that the molecule was not a DNA. This is because RNA degrading enzymes had no effect on the transforming principle and only RNase-treated heat-killed cell extracts are unable to transform non-virulent bacteria into virulent bacteria.
