Assertion Explanation
The assertion states that "DNA is considered to be better genetic material than RNA for most organisms." This is true because:
- DNA is more stable due to its double-stranded structure.
- It is less prone to chemical degradation, making it a reliable carrier of genetic information.
- The stability of DNA allows it to serve as a long-term storage medium for genetic information in cells.
Reason Explanation
The reason provided is that "the 2-OH group present in DNA makes it labile and less reactive." This statement is false because:
- The 2-OH (hydroxyl) group is found in RNA, not DNA; DNA has a 2-deoxyribose sugar, which lacks this hydroxyl group.
- The presence of the 2-OH group in RNA contributes to its reactivity, making RNA more prone to hydrolysis and degradation compared to DNA.
- Therefore, it's the lack of the 2-OH group in DNA that contributes to its stability as genetic material.
Conclusion
Based on the explanations:
- The assertion is true as DNA is indeed the more stable genetic material for most organisms.
- The reason is false since the 2-OH group is not present in DNA and does not contribute to its lability or reactivity.
Thus, the correct answer is option 'C': If Assertion is true but Reason is false.

The genetic material should be stable enough not to change with different stages of life cycle, age or with change in physiology of the organism. The DNA strands being complementary, if separated by heating come together only when appropriate conditions are provided. Further, 2'-OH group present at every nucleotide in RNA is a reactive group and makes RNA labile and easily degradable. RNA is also now known to be catalytic, hence reactive. Therefore, DNA chemically is less reactive and structurally more stable when compared to RNA. Therefore, among the two nucleic acids, DNA is a better genetic material.
