Question

In the Avery, McCleod, and McCarty experiment, live or heat killed virulent S strain bacterial cells (kill mice) and avirulent R strain bacterial cells (do not kill mice) were mixed with each other and with various enzymes before injecting into mice. Which of the following combinations of treatments would result in a transformation event such that transformed bacteria generated after the mixing of these materials would kill mice when injected into them?

i. heat killed S bacteria + heat killed R bacteria + protease
ii. heat killed S bacteria + heat killed R bacteria + RNAse
iii. heat killed S bacteria + heat killed R bacteria + DNAse
iv. heat killed S bacteria + live R bacteria + protease
v. heat killed S bacteria + live R bacteria + RNAse
vi. heat killed S bacteria + live R bacteria + DNAse
vii. heat killed R bacteria + live S bacteria + protease
viii. heat killed R bacteria + live S bacteria + RNAse
ix. heat killed R bacteria + live S bacteria + DNAse
