Chemically, RNA is (i)_____ reactive and (ii)_____ stable as compared to DNA.

Options

A. (i)equally , (ii) equally
B. (i)less , (ii) more
C. (i)more , (ii)less
D. (i)more , (ii)equally

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks us to compare the chemical reactivity and stability of RNA in relation to DNA.

2. **Defining RNA and DNA**:
- RNA (Ribonucleic Acid) is typically single-stranded and plays a crucial role in various biological processes, including acting as a messenger and a catalyst.
- DNA (Deoxyribonucleic Acid) is usually double-stranded and serves as the genetic blueprint for living organisms.

3. **Analyzing Reactivity**:
- RNA is known to be chemically reactive. This is due to the presence of a hydroxyl group (-OH) on the 2' carbon of the ribose sugar in RNA, which makes it more prone to hydrolysis and other chemical reactions.
- In contrast, DNA lacks this hydroxyl group (it has a hydrogen atom instead), making it less reactive.

4. **Analyzing Stability**:
- Due to its reactivity, RNA is also considered less stable compared to DNA. The single-stranded nature of RNA makes it more susceptible to degradation.
- DNA's double-stranded structure provides a more stable configuration, protecting it from enzymatic degradation and environmental factors.

5. **Conclusion**:
- Therefore, we can conclude that chemically, RNA is **(i) more reactive** and **(ii) less stable** compared to DNA.

**Final Answer**:
Chemically, RNA is (i) **more** reactive and (ii) **less** stable as compared to DNA.
