Q. Which one of the following suggested that DNA causes the transformation of R strain into S strain?
- Biochemicals of heat-killed S strain + R strain ----(DNAse) --------> Live S strain
- Biochemicals of heat-killed S strain + R strain -----(RNAse) --------> R strain
- Biochemicals of heat-killed S strain + R strain -----(Proteinase) -------> Live S strain
- Biochemicals of heat-killed S strain + R strain -----(DNAse) -------> R strain
Q. The first concluding proof that DNA is the hereditary material was given by
- Avery, MacLeod and McCarty
- Hershey and Chase
- Griffith
- Watson and Crick
Q. Avery, MacLeod and McCarty observed that in the experimental tubes to which RNAse and proteinase were added, transformation could happen. This indicated that
- RNA is the transforming principle
- Protein is the transforming principle
- Neither RNA nor protein could be the transforming principle
- None of the above
Q. Among the following, identify the correct option that does not show transformation of R strain into S strain?
- S strain (heat killed) + R strain (live)
- S strain (heat killed) + R strain (live) + Protease
- S strain (heat killed) + R strain (live) + RNase
- S strain (heat killed) + R strain (live) + DNase
