Complete hydrolysis of DNA/RNA yields

Options

A. a pentose sugar
B. phosphoric acid
C. base (Nitrogen containing heterocyclic compounds)
D. All of the above

Explanation

To answer the question "Complete hydrolysis of DNA/RNA yields," we will break down the components produced during the hydrolysis process.

### Step-by-Step Solution:

1. **Understanding Nucleotides**:
- DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid) are polymers made up of monomer units called nucleotides.
- Each nucleotide consists of three components: a phosphate group, a sugar (pentose), and a nitrogenous base.

2. **Components of Nucleotides**:
- **Phosphate Group**: This is a key component of both DNA and RNA.
- **Sugar**:
- In DNA, the sugar is deoxyribose.
- In RNA, the sugar is ribose.
- Both sugars are classified as pentose sugars.
- **Nitrogenous Bases**:
- DNA contains adenine (A), guanine (G), cytosine (C), and thymine (T).
- RNA contains adenine (A), guanine (G), cytosine (C), and uracil (U).

3. **Hydrolysis Process**:
- During complete hydrolysis of DNA or RNA, the bonds between the nucleotides are broken down, resulting in the release of the individual components:
- **Pentose Sugars**: Both DNA and RNA yield pentose sugars upon hydrolysis.
- **Phosphoric Acid**: The phosphate groups are released as phosphoric acid.
- **Nitrogenous Bases**: The nitrogen bases are also released.

4. **Final Outcome**:
- Therefore, the complete hydrolysis of DNA and RNA yields:
- Pentose sugars
- Phosphoric acid
- Nitrogenous bases

5. **Conclusion**:
- Since all the components mentioned above are produced during hydrolysis, the correct answer to the question is **Option D: All of the above**.
