Choose the correct statement in the following
Choose the correct statement in the following
Show Hint
Transformation experiments confirmed DNA as the genetic material, not protein or RNA.
Updated On: Jun 3, 2025
- In Griffith’s transforming principle, digestion with DNase did inhibit transformation whereas proteases and RNase did not affect transformation.
- Virus grown in radioactive sulphur contained radioactive protein and radioactive DNA.
- Virus grown in radioactive phosphorous contain radioactive protein and non-radioactive DNA.
- Mice infected R strain die from pneumonia, but mice infected from S strain do not develop pneumonia.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In Avery, MacLeod and McCarty’s extension of Griffith’s experiment, DNase inhibited transformation, confirming DNA as the genetic material.
RNase and protease had no effect.

Top Questions on Biomolecules
- Ribose and 2-deoxyribose have an important role in biology. Among the most important derivatives are those with phosphate groups attached at the 5 position. Mono-, di- and tri-phosphate forms are important, as well as 3-5 cyclic monophosphates. Purines and pyrimidines form an important class of compounds with ribose and deoxyribose. When these purine and pyrimidine derivatives are coupled to a ribose sugar, they are called nucleosides.
